Data Science for Economics

Many of the most pressing questions in empirical economics concern causal questions, such as the impact, both short and long run, of educational choices on labor market outcomes, and of economic policies on distributions of outcomes. This makes them conceptually quite different from the predictive type of questions that many of the recently developed methods in machine learning are primarily designed for.

Data Science for Education

Educational data spans K-12 school and district records, digital archives of instructional materials and gradebooks, as well as student responses on course surveys. Data science of actual classroom interaction is also of increasing interest and reality.

Data Science for Human Health

It is clear that data science will be a driving force in transitioning the world’s healthcare systems from reactive “sick-based” care to proactive, preventive care.

Data Science for Humanity

Our modern era is characterized by massive amounts of data documenting the behaviors of individuals, groups, organizations, cultures, and indeed entire societies. This wealth of data on modern humanity is accompanied by massive digitization of historical data, both textual and numeric, in the form of historic newspapers, literary and linguistic corpora, economic data, censuses, and other government data, gathered and preserved over centuries, and newly digitized, acquired, and provisioned by libraries, scholars, and commercial entities.

Data Science for Linguistics

The impact of data science on linguistics has been profound. All areas of the field depend on having a rich picture of the true range of variation, within dialects, across dialects, and among different languages. The subfield of corpus linguistics is arguably as old as the field itself and, with the advent of computers, gave rise to many core techniques in data science.

Data Science for Nature and Sustainability

Many key sustainability issues translate into decision and optimization problems and could greatly benefit from data-driven decision making tools. In fact, the impact of modern information technology has been highly uneven, mainly benefiting large firms in profitable sectors, with little or no benefit in terms of the environment. Our vision is that data-driven methods can — and should — play a key role in increasing the efficiency and effectiveness of the way we manage and allocate our natural resources.

Ethics and Data Science

With the emergence of new techniques of machine learning, and the possibility of using algorithms to perform tasks previously done by human beings, as well as to generate new knowledge, we again face a set of new ethical questions.

The Science of Data Science

The practice of data analysis has changed enormously. Data science needs to find new inferential paradigms that allow data exploration prior to the formulation of hypotheses.

Ten Research Challenge Areas in Data Science

Although data science builds on knowledge from computer science, mathematics, statistics, and other disciplines, data science is a unique field with many mysteries to unlock: challenging scientific questions and pressing questions of societal importance.

Is data science a discipline?

Data science is a field of study: one can get a degree in data science, get a job as a data scientist, and get funded to do data science research.  But is data science a discipline, or will it evolve to be one, distinct from other disciplines?  Here are a few meta-questions about data science as a discipline.

• What is/are the driving deep question(s) of data science?   Each scientific discipline (usually) has one or more “deep” questions that drive its research agenda: What is the origin of the universe (astrophysics)?  What is the origin of life (biology)?  What is computable (computer science)?  Does data science inherit its deep questions from all its constituency disciplines or does it have its own unique ones?
• What is the role of the domain in the field of data science?   People (including this author) (Wing, J.M., Janeia, V.P., Kloefkorn, T., & Erickson, L.C. (2018)) have argued that data science is unique in that it is not just about methods, but about the use of those methods in the context of a domain—the domain of the data being collected and analyzed; the domain for which a question to be answered comes from collecting and analyzing the data.  Is the inclusion of a domain inherent in defining the field of data science?  If so, is the way it is included unique to data science?
• What makes data science data science?   Is there a problem unique to data science that one can convincingly argue would not be addressed or asked by any of its constituent disciplines, e.g., computer science and statistics?

Ten research areas

While answering the above meta-questions is still under lively debate, including within the pages of this  journal, we can ask an easier question, one that also underlies any field of study: What are the research challenge areas that drive the study of data science?  Here is a list of ten.  They are not in any priority order, and some of them are related to each other.  They are phrased as challenge areas, not challenge questions.  They are not necessarily the “top ten” but they are a good ten to start the community discussing what a broad research agenda for data science might look like. 1

• Scientific understanding of learning, especially deep learning algorithms.    As much as we admire the astonishing successes of deep learning, we still lack a scientific understanding of why deep learning works so well.  We do not understand the mathematical properties of deep learning models.  We do not know how to explain why a deep learning model produces one result and not another.  We do not understand how robust or fragile they are to perturbations to input data distributions.  We do not understand how to verify that deep learning will perform the intended task well on new input data.  Deep learning is an example of where experimentation in a field is far ahead of any kind of theoretical understanding.
• Causal reasoning.   Machine learning is a powerful tool to find patterns and examine correlations, particularly in large data sets. While the adoption of machine learning has opened many fruitful areas of research in economics, social science, and medicine, these fields require methods that move beyond correlational analyses and can tackle causal questions. A rich and growing area of current study is revisiting causal inference in the presence of large amounts of data.  Economists are already revisiting causal reasoning by devising new methods at the intersection of economics and machine learning that make causal inference estimation more efficient and flexible (Athey, 2016), (Taddy, 2019).  Data scientists are just beginning to explore multiple causal inference, not just to overcome some of the strong assumptions of univariate causal inference, but because most real-world observations are due to multiple factors that interact with each other (Wang & Blei, 2018).
• Precious data.    Data can be precious for one of three reasons: the dataset is expensive to collect; the dataset contains a rare event (low signal-to-noise ratio );  or the dataset is artisanal—small and task-specific.   A good example of expensive data comes from large, one-of, expensive scientific instruments, e.g., the Large Synoptic Survey Telescope, the Large Hadron Collider, the IceCube Neutrino Detector at the South Pole.  A good example of rare event data is data from sensors on physical infrastructure, such as bridges and tunnels; sensors produce a lot of raw data, but the disastrous event they are used to predict is (thankfully) rare.   Rare data can also be expensive to collect.  A good example of artisanal data is the tens of millions of court judgments that China has released online to the public since 2014 (Liebman, Roberts, Stern, & Wang, 2017) or the 2+ million US government declassified documents collected by Columbia’s  History Lab  (Connelly, Madigan, Jervis, Spirling, & Hicks, 2019).   For each of these different kinds of precious data, we need new data science methods and algorithms, taking into consideration the domain and intended uses of the data.
• Multiple, heterogeneous data sources.   For some problems, we can collect lots of data from different data sources to improve our models.  For example, to predict the effectiveness of a specific cancer treatment for a human, we might build a model based on 2-D cell lines from mice, more expensive 3-D cell lines from mice, and the costly DNA sequence of the cancer cells extracted from the human. State-of-the-art data science methods cannot as yet handle combining multiple, heterogeneous sources of data to build a single, accurate model.  Since many of these data sources might be precious data, this challenge is related to the third challenge.  Focused research in combining multiple sources of data will provide extraordinary impact.
• Inferring from noisy and/or incomplete data.   The real world is messy and we often do not have complete information about every data point.  Yet, data scientists want to build models from such data to do prediction and inference.  A great example of a novel formulation of this problem is the planned use of differential privacy for Census 2020 data (Garfinkel, 2019), where noise is deliberately added to a query result, to maintain the privacy of individuals participating in the census. Handling “deliberate” noise is particularly important for researchers working with small geographic areas such as census blocks, since the added noise can make the data uninformative at those levels of aggregation. How then can social scientists, who for decades have been drawing inferences from census data, make inferences on this “noisy” data and how do they combine their past inferences with these new ones? Machine learning’s ability to better separate noise from signal can improve the efficiency and accuracy of those inferences.
• Trustworthy AI.   We have seen rapid deployment of systems using artificial intelligence (AI) and machine learning in critical domains such as autonomous vehicles, criminal justice, healthcare, hiring, housing, human resource management, law enforcement, and public safety, where decisions taken by AI agents directly impact human lives. Consequently, there is an increasing concern if these decisions can be trusted to be correct, reliable, robust, safe, secure, and fair, especially under adversarial attacks. One approach to building trust is through providing explanations of the outcomes of a machine learned model.  If we can interpret the outcome in a meaningful way, then the end user can better trust the model.  Another approach is through formal methods, where one strives to prove once and for all a model satisfies a certain property.  New trust properties yield new tradeoffs for machine learned models, e.g., privacy versus accuracy; robustness versus efficiency. There are actually multiple audiences for trustworthy models: the model developer, the model user, and the model customer.  Ultimately, for widespread adoption of the technology, it is the public who must trust these automated decision systems.
• Computing systems for data-intensive applications.    Traditional designs of computing systems have focused on computational speed and power: the more cycles, the faster the application can run.  Today, the primary focus of applications, especially in the sciences (e.g., astronomy, biology, climate science, materials science), is data.  Also, novel special-purpose processors, e.g., GPUs, FPGAs, TPUs, are now commonly found in large data centers. Even with all these data and all this fast and flexible computational power, it can still take weeks to build accurate predictive models; however, applications, whether from science or industry, want  real-time  predictions.  Also, data-hungry and compute-hungry algorithms, e.g., deep learning, are energy hogs (Strubell, Ganesh, & McCallum, 2019).   We should consider not only space and time, but also energy consumption, in our performance metrics.  In short, we need to rethink computer systems design from first principles, with data (not compute) the focus.  New computing systems designs need to consider: heterogeneous processing; efficient layout of massive amounts of data for fast access; the target domain, application, or even task; and energy efficiency.
• Automating front-end stages of the data life cycle.   While the excitement in data science is due largely to the successes of machine learning, and more specifically deep learning, before we get to use machine learning methods, we need to prepare the data for analysis.  The early stages in the data life cycle (Wing, 2019) are still labor intensive and tedious.  Data scientists, drawing on both computational and statistical methods, need to devise automated methods that address data cleaning and data wrangling, without losing other desired properties, e.g., accuracy, precision, and robustness, of the end model.One example of emerging work in this area is the Data Analysis Baseline Library (Mueller, 2019), which provides a framework to simplify and automate data cleaning, visualization, model building, and model interpretation.  The Snorkel project addresses the tedious task of data labeling (Ratner et al., 2018).
• Privacy.   Today, the more data we have, the better the model we can build.  One way to get more data is to share data, e.g., multiple parties pool their individual datasets to build collectively a better model than any one party can build.  However, in many cases, due to regulation or privacy concerns, we need to preserve the confidentiality of each party’s dataset.  An example of this scenario is in building a model to predict whether someone has a disease or not. If multiple hospitals could share their patient records, we could build a better predictive model; but due to Health Insurance Portability and Accountability Act (HIPAA) privacy regulations, hospitals cannot share these records. We are only now exploring practical and scalable ways, using cryptographic and statistical methods, for multiple parties to share data and/or share models to preserve the privacy of each party’s dataset.  Industry and government are exploring and exploiting methods and concepts, such as secure multi-party computation, homomorphic encryption, zero-knowledge proofs, and differential privacy, as part of a point solution to a point problem.
• Ethics.   Data science raises new ethical issues. They can be framed along three axes: (1) the ethics of data: how data are generated, recorded, and shared; (2) the ethics of algorithms: how artificial intelligence, machine learning, and robots interpret data; and (3) the ethics of practices: devising responsible innovation and professional codes to guide this emerging science (Floridi & Taddeo, 2016) and for defining Institutional Review Board (IRB) criteria and processes specific for data (Wing, Janeia, Kloefkorn, & Erickson 2018). Example ethical questions include how to detect and eliminate racial, gender, socio-economic, or other biases in machine learning models.

Closing remarks

As many universities and colleges are creating new data science schools, institutes, centers, etc. (Wing, Janeia, Kloefkorn, & Erickson 2018), it is worth reflecting on data science as a field.  Will data science as an area of research and education evolve into being its own discipline or be a field that cuts across all other disciplines?  One could argue that computer science, mathematics, and statistics share this commonality: they are each their own discipline, but they each can be applied to (almost) every other discipline. What will data science be in 10 or 50 years?

• Data Science Project Ideas: Next Steps\

End-to-end projects involve real-world problems which you solve using the 6 stages of the data science life cycle:

• Business understanding
• Data understanding
• Data preparation

Here’s how to execute a data science project from end to end in more detail.

First, you define the business questions, requirements, and performance measurement. After that, you collect data to answer these questions. Then come the cleaning and preparation processes to get the data ready for exploration and analysis. These are the understanding stages.

But we’re not done yet.

Next comes the data preparation process. It involves the preprocessing and engineering of the features to prepare for the modeling step. Once that’s done, you can train the models on the prepared data. Depending on the task you are working on, you can do one of two things:

• Deploy the model on a live server and integrate it into a mobile or web application; then, monitor it and iterate again if needed, or
• Build dashboards based on the insights extracted from the data and the modeling step.

That wraps up the data science life cycle. Before you start working, you need some ideas for a data science project.

For starters, select a domain you are interested in. You can choose one that fits your educational background or previous work experience. This will give you a head start as you will know the field.

After that, you need to explore the common problems in this domain and how data science can solve them. Finally, choose a case study and formulate the business questions. Only then can you apply the life cycle we discussed above.

Now, let’s get started with a few project ideas.

The increasing cost of healthcare services is a major concern, especially for patients in the US. However, if planned properly, it can be reduced significantly.

The purpose of this project is to predict hospital charges before admitting a patient. Data science projects like this one are a great addition to your portfolio, especially if you want to pursue a career in healthcare .

Project Description

This will allow people to compare the costs at different medical institutions and plan their finances accordingly in case of elective admissions. It will also enable insurance companies to predict how much a patient with a particular medical condition might claim after a hospitalization.

You can solve this project using predictive analysis . This type of advanced analytics allows us to make predictions about future outcomes based on historical data. Typically, it involves statistical modeling, data mining, and machine learning techniques. In this case, we estimate hospital treatment costs based on the patient’s clinical data at admission.

Methodology

• Collect the hospital package pricing dataset
• Explore and understand the data
• Clean the data
• Perform engineering and preprocessing to prepare for the modeling step
• Select the suitable predictive model and train it with the data

• Monitor the model in production and iterate

Expected Output

There are two expected outputs from this project:

• Analytical dashboard with insights extracted from the data that can be delivered to hospital and insurance companies
• Deployed predictive model into production on a live server that can be integrated into a web or mobile application and predict treatment costs in real time

Suggest Dataset:

• Package Pricing at Mission Hospital

Research Paper:

• Predicting the Inpatient Hospital Cost Using Machine Learning

This following example is form the marketing and finance domain .

Sentiment analysis or opinion mining refers to the analysis of the attitudes, feedback, and emotions users express on social media and other online platforms. It involves the detection of patterns in natural language that allude to people’s attitudes toward certain products or topics.

YouTube is the second most popular website in the world. Its comments section is a great source of user opinions on various topics. There are many examples of how you can approach such a data science project.

Let’s explore one of them.

You can analyze YouTube comments with natural language processing techniques. Begin by scraping text data using the library YouTube-Comment-Scraper-Python. It fetches comments utilizing browser automation.

Marine life has a significant impact on our planet, providing food, oxygen, and biodiversity. Unfortunately, 90% of the large fish are gone primarily as a result of overfishing . In addition, many major fisheries notice increases in illegal fishing, undermining the efforts to conserve and manage fish stocks.

Detecting fishing activities in the ocean is a crucial step in achieving sustainability. It’s also an excellent big data project to add to your portfolio.

Identifying whether a vessel is fishing illegally and where this activity is likely to occur is a major step in ending illegal, unreported, and unregulated (IUU) fishing. However, monitoring the oceans is costly, time-consuming, and logistically difficult.

To overcome these challenges, we must improve the ability to detect and predict illegal fishing. This can be done using classification machine learning models to recognize and trace illegal fishing activity by collecting and processing GPS data from ships, as well as other pieces of information. The classification algorithm can distinguish these ships by type, fishing gear, and fishing behaviors.

• Collect the fishing watch dataset
• Perform data exploration to understand it better
• Perform engineering to extract features from the data
• Train classification models to categorize the fishing activity
• Deploy the trained model on a live server and integrate it into a web application
• Finish by monitoring the model in production and iterating

Deployed model running in a live server and used within a web service or mobile application to predict illegal fishing in real time.

Suggested Dataset

• Global Fishing Watch datasets

Dogecoin became one of the most popularity cryptocurrencies in recent years. Its price peaked in 2021, and it’s been slowly decreasing in 2022. That’s the case with most cryptocurrencies in the current economic situation.

However, the constant fluctuations make it hard for a human being to predict with accuracy the future prices. As such, automated algorithms are commonly used in finance .

This is an extremely valuable data science project for your resume if you want to pursue a career in this domain. If that’s your goal, you also need to learn how to use Python for Finance .

In this section, we discuss a time series forecasting project, commonly encountered in the financial sector .

A time series is a sequence of data points distributed over a time span. With forecasting, we can recognize patterns and predict future incidents based on historical trends. This type of data analytics projects can be conducted using several models, including ARIMA (autoregressive integrated moving average), regression algorithms, and long short-term memory (LSTM).

• Collect the historical price data of the Dogecoin cryptocurrency
• Manipulate and clean the data
• Explore the data to have a better understanding
• Train a deep learning model to predict the future change in prices

Project Overview

Flawed products can result in substantial financial losses, so defect detection is crucial in manufacturing. Although human detection systems are still the traditional method employed, computer vision techniques are more effective.

In this example, we build a system to detect defects in metallic objects or surfaces during different phases of the production processes.

The types of defects can be aesthetic, such as stains, or potentially damaging the product’s functionality, such as notches, scratches, burns, lack of rectification, bumps, burrs, flatness, lack of thread, countersunk, rust, or cracks.

Since the appearance of metallic surfaces changes substantially with different lighting, defects are hard to detect even using computer vision. For this reason, lighting is a crucial component in solving such types of data science problems. Otherwise, the methodology of this project is standard.

• Collect the metal surface defects dataset
• Data cleaning and exploration
• Feature extraction
• Train models for defects detection and classification
• Deploy the model into production on an embedded system

A deployed model on an embedded system that can detect and classify metallic surface defects in different conditions and environments.

A Guide to Data Science Research Projects

Ria Cheruvu

Towards Data Science

Starting a data science research project can be challenging, whether you’re a novice or a seasoned engineer — you want your project to be meaningful , accessible , and valuable to the data science community and your portfolio. In this post, I’ll introduce two frameworks you can use as a guide for your data science research projects. Please note this guide isn’t mean to be exhaustive — it’s based on my experiences working with data science and machine learning that I think can be helpful for beginner data scientists.

Research Process — Ideation to Implementation

• Identify the research problem you want to explore or solve.
• Ask yourself the following questions:
• Do I want to focus on engineering work or pure research?

For example, if you are building a new machine learning application, engineering might involve building a framework and user interface for the algorithm and using deployment infrastructures to speed up data access.

Pure research can involve trying to manipulate the properties of the model in innovative ways (e.g., create a new loss function) or to create an entirely new model, such as the type of research you see in papers from NeurIPS and similar conferences.

It is possible to also do a blend of engineering and pure research — you need to think about the approach that best fits the research goal.

• Is the goal of my research to outperform an existing baseline (e.g., get the highest score for the ImageNet dataset), or to explore a research field using an innovative methodology where a solid baseline may not have been already established? Both types of research problems are valuable for data science.

3. Perform a literature review. Look at existing work in the field and analyze the strengths and weaknesses of relevant methodologies. Identify gaps in the literature you are interested in exploring.

4. Design your proposed solution and implement a baseline/prototype (see the development process below).

5. Iteratively develop the prototype, based on your answers from Step 2.

Development Process — Prerequisites

The goal of the following steps is to guide you to pick the optimal data storage option, machine learning model, and development and deployment processes for your use case. After outlining these aspects, I recommend the development process can then be started.

• What is the type of the data and how will it be stored?
• If the variable you are attempting to predict is numerical, you could define your problem statement as a normal regression application. Few of the popular ML models for approaching this are linear regression, decision trees, support vector machines, and neural networks or deep learning.
• If the data is ordered by time, you could consider time series methods — there are traditional algorithms for this in addition to deep learning methods.
• If you are working with a large amount of data, depending on the data format, you could consider exploring big data storage and processing solutions, such as Apache Spark, Cassandra, Redis, etc. Some of the big data storage solutions easily and natively support machine learning tools/algorithms.

2. Where will the model be hosted and how will it be deployed? Can the deliverable be structured as a pipeline or system, and if so, what do the inputs and outputs if the system look like?

As part of this step, you’ll need to ask the question: “Are there any constraints on the types of models that I can use?” For example, will the model be used for a streaming data application (data is fed to the model consistently over certain time periods, such as 1 hour) or a typical prediction on a large dataset? Will your users access the model via command line or a web page?

You could consider using tools like Luigi and Apache AirFlow to help with the pipelining and workflow management of your project.

3. What are the critical and good-to-have characteristics of the models I am looking for and what ML algorithms fit that description?

To answer this, you’ll need to circle back to the goal of your project. Here are some example questions you might ask:

• Is your goal to predict and improve a certain factor or event based on data?
• Do you think understanding the features your algorithm is using to make a prediction is important (e.g., to understand how to improve that certain factor/event)?

This might determine your model choice. For example, with decision trees, you can identify which features your algorithm is considering most important for the prediction and the decision path, but these models may not provide great accuracy for your application. However, neural networks could provide great accuracy, but are more challenging to interpret.

There are solutions that allow you to get both interpretability and good accuracy. For example, neural networks and decision trees can be combined through Neural-Backed Decision Trees , although these approaches may have certain trade-offs (e.g., requiring pre-trained weights). You’ll need to investigate the pros and cons of the approaches you’re considering to evaluate how they fit into your problem statement.

4. How will you debug and evaluate your models? What are the metrics you will consider and any visualizations?

• The metrics you choose can be dependent on existing approaches in the literature, which you may have identified during the research process. For example, you may choose to include Matthews Correlation Coefficient or balanced accuracy, in addition to the original accuracy metric, when working with imbalanced data.
• As you consider what tools and processes you will implement for your pipeline, remember to document any important changes in hyperparameters you may make to your models or use a tool such as Weights and Biases , for debug purposes.
• Visualizations are an important part of the development process — they can be used for debugging your model (e.g., learning curves), interpretability (e.g., salience maps), and for data analysis and final reporting (e.g., word clouds). Before starting your development, try to think about the types of visualizations that can add to the implementation, quality, and value of your project.

Each step within these two frameworks requires some thought, and trial and error. I’ll be covering some helpful tips on these steps in future blog posts, so if you found this post helpful, stay tuned for more!

We collected some basic and advanced topics in data science to give you ideas on where to master your skills.

In today’s landscape, businesses are investing in corporate data science training to enhance their employees’ data science capabilities.

Data science topics also are hot subjects you can use as directions to prepare yourself for data science job interview questions.

1. The core of data mining process

This is an example of a wide data science topic.

What is it?

Data mining is an iterative process that involves discovering patterns in large data sets. It includes methods and techniques such as machine learning, statistics, database systems and etc.

The two main data mining objectives are to find out patterns and establish trends and relationship in a dataset in order to solve problems.

The general stages of the data mining process are: problem definition, data exploration, data preparation, modeling, evaluation, and deployment.

Core terms related to data mining are classification, predictions, association rules, data reduction, data exploration, supervised and unsupervised learning, datasets organization, sampling from datasets, building a model and etc.

2. Data visualization

Data visualization is the presentation of data in a graphical format.

It enables decision-makers of all levels to see data and analytics presented visually, so they can identify valuable patterns or trends.

Data visualization is another broad subject that covers the understanding and use of basic types of graphs (such as line graphs, bar graphs, scatter plots , histograms, box and whisker plots , heatmaps.

You cannot go without these graphs. In addition, here you need to learn about multidimensional variables with adding variables and using colors, size, shapes, animations.

Manipulation also plays a role here. You should be able to rascal, zoom, filter, aggregate data.

Using some specialized visualizations such as map charts and tree maps is a hot skill too.

3. Dimension reduction methods and techniques

Dimension Reduction process involves converting a data set with vast dimensions into a dataset with lesser dimensions ensuring that it provides similar information in short.

In other words, dimensionality reduction consists of series of techniques and methods in machine learning and statistics to decrease the number of random variables.

There are so many methods and techniques to perform dimension reduction.

The most popular of them are Missing Values, Low Variance, Decision Trees, Random Forest, High Correlation, Factor Analysis, Principal Component Analysis, Backward Feature Elimination.

4. Classification

Classification is a core data mining technique for assigning categories to a set of data.

The purpose is to support gathering accurate analysis and predictions from the data.

Classification is one of the key methods for making the analysis of a large amount of datasets effective.

Classification is one of the hottest data science topics too. A data scientist should know how to use classification algorithms to solve different business problems.

This includes knowing how to define a classification problem, explore data with univariate and bivariate visualization, extract and prepare data, build classification models, evaluate models, and etc. Linear and non-linear classifiers are some of the key terms here.

5. Simple and multiple linear regression

Linear regression models are among the basic statistical models for studying relationships between an independent variable X and Y dependent variable.

It is a mathematical modeling which allows you to make predictions and prognosis for the value of Y depending on the different values of X.

There are two main types of linear regression: simple linear regression models and multiple linear regression models.

Key points here are terms such as correlation coefficient, regression line, residual plot, linear regression equation and etc. For the beginning, see some simple linear regression examples .

6. K-nearest neighbor (k-NN) 

N-nearest-neighbor is a data classification algorithm that evaluates the likelihood a data point to be a member of one group. It depends on how near the data point is to that group.

As one of the key non-parametric method used for regression and classification, k-NN can be classified as one of the best data science topics ever.

Determining neighbors, using classification rules, choosing k are a few of the skills a data scientist should have. K-nearest neighbor is also one of the key text mining and anomaly detection algorithms .

7. Naive Bayes

Naive Bayes is a collection of classification algorithms which are based on the so-called Bayes Theorem .

Widely used in Machine Learning, Naive Bayes has some crucial applications such as spam detection and document classification.

There are different Naive Bayes variations. The most popular of them are the Multinomial Naive Bayes, Bernoulli Naive Bayes, and Binarized Multinomial Naive Bayes.

8. Classification and regression trees (CART)

When it comes to algorithms for predictive modeling machine learning, decision trees algorithms have a vital role.

The decision tree is one of the most popular predictive modeling approaches used in data mining, statistics and machine learning that builds classification or regression models in the shape of a tree (that’s why they are also known as regression and classification trees).

They work for both categorical data and continuous data.

Some terms and topics you should master in this field involve CART decision tree methodology, classification trees, regression trees, interactive dihotomiser, C4.5, C5.5, decision stump, conditional decision tree, M5, and etc.

9. Logistic regression

Logistic regression is one of the oldest data science topics and areas and as the linear regression, it studies the relationship between dependable and independent variable.

However, we use logistic regression analysis where the dependent variable is dichotomous (binary).

You will face terms such as sigmoid function, S-shaped curve, multiple logistic regression with categorical explanatory variables, multiple binary logistic regression with a combination of categorical and continuous predictors and etc.

10. Neural Networks

Neural Networks act as a total hit in the machine learning nowadays. Neural networks (also known as artificial neural networks) are systems of hardware and/or software that mimic the human brain neurons operation.

The above were some of the basic data science topics. Here is a list of more interesting and advanced topics:

11. Discriminant analysis

12. Association rules

13. Cluster analysis

14. Time series

15. Regression-based forecasting

16. Smoothing methods

• Important Computer Science Trends
• Top Cryptocurrency Trends
• Important Technology Trends

Here are the 8 fastest-growing data science trends for 2024 and beyond. 

We'll also outline how these trends will impact both data scientists’ work and everyday life.

Whether you’re actively involved in the data science community, or just concerned about your data privacy, these are the top trends to know.

1. Generative AI use continues to grow

Generative AI is impacting nearly every industry, from  advertising to computer science .

Notably, it looks like generative AI usage is poised for even more growth in 2024 and 2025.

Google found that 64% of developers feel a "sense of urgency" to use generative AI.

And another survey of business leaders found that 85% of them plan to use AI to replace low-level tasks by the end of 2024. 

However, there's skepticism within the data science field whether generative AI is living up to the hype.

One survey by MIT found that 52% of tech CEOs were interested in using generative AI in their organizations.

However, only 13% had an actual plan for doing so.

And others in tech are concerned that over-reliance on AI could cause issues in the future.

In fact, Sourcegraph discovered that 76% of developers are excited by the potential that AI brings to the table. 

However, there were also significant concerns about AI leading to increased tech debt, sprawl, and code to manage .

2. Explosion in deepfake video and audio

Deepfakes use artificial intelligence to manipulate or create content to represent someone else.

Often this is an image or video of one person modified to someone else’s likeness.

But it can be audio too.

An AI company deepfaked popular podcaster Joe Rogan’s voice so effectively it instantly went viral on social media.

And, thanks to advancements in generative AI, the tech has only improved since.

There’s huge scope for this technology to be used maliciously.

Another voice deep fake was used to scam a UK-based energy company out of €220,000 .

The CEO believed he was on the phone with a colleague and was told to urgently transfer the money to the bank account of a Hungarian supplier.

In fact, the call had been spoofed with deep fake technology to mimic the man’s voice and “melody”.

In fact, there's growing search interest in a practice known as "voice phishing". Which is essentially the "official" term for the practice.

As well as hoaxes and financial fraud, deepfakes can also be weaponized to discredit business figures and politicians.

Governments are starting to protect against this with legislation and social media regulation.

And with technology that can identify deepfake videos.

But the battle with deepfakes has only just begun.

3. More applications created with Python

Python is the go-to programming language for data analysis.

Why is this?

Because Python has a huge number of free data science libraries such as Pandas and machine learning libraries like Scikit-learn .

It can even be used to develop blockchain applications.

Add to this a friendly learning curve for beginners, and you have a recipe for success.

According to Stack Overflow, Python is now the 4th most popular language in general .

(Only behind mainstays like JavaScript, HTML and SQL).

And the popularity growth trend shows it’s has the potential to be #2 or even #1 within the next few years. 

4. Increased demand for End-to-end AI solutions

Enterprise AI company Dataiku is now worth $4.6 billion ( according to TechCrunch ) after Google bought a stake in the company.

The AI startup helps enterprise customers clean their large data sets and build machine learning models.

This way, companies like General Electric and Unilever can gain valuable, deep-learning insights from their massive amounts of data.

And automate important data management tasks.

Previously, businesses would have to seek expertise in all the different parts of the process and piece it together themselves.

But Dataiku handles the entire data science cycle from start to finish with a single product.

And because of this, they stand out.

Businesses want end-to-end data science solutions. And startups that provide this will eat the market.

5. Companies hire more data analysts

Demand for data analysts has shot through the roof over the last few years.

And, thanks largely to data coming in from the Internet of Things (IoT) and advances in cloud computing, global data storage is set to grow from 45 zettabytes to 175 zettabytes by 2025 .

So the need for experts to parse and analyze all of this data is set to rise.

Why are so many data analysts required?

After all, there are plenty of data analytics programs out there that can sort through it all.

And "digital transformation" has supposedly replaced many human-led business tasks.

Sure, machines can help analyze data.

But big data is often extremely messy and lacking in proper structure.

Which is why humans are needed to manually tidy training data before it is ingested by machine learning algorithms.

It’s also increasingly common for data people to be involved on the output end too.

AI-produced results are not always reliable or accurate, so machine learning companies often use humans to clean up the final data.

And write up an analysis of what they find in a way that non-tech stakeholders can understand it.

The data science and machine learning methods of the 2020s will be less artificial and automated than initially expected.

Augmented intelligence and human-in-the-loop artificial intelligence will likely become a big trend in data science.

6. Data scientists joining Kaggle

Kaggle has grown quickly to become the world's largest data science community.

And with over 15 million users across 194 countries, it’s not slowing down.

Many budding data scientists now start with Kaggle to begin their machine learning journey. 

And post the progress of their machine learning projects in real-time.

Users can even share data sets and enter competitions to solve data science challenges with neural networks.

Or work with other data scientists to build models in Kaggle’s web-based data science workbench.

Academic papers have actually been published based on Kaggle competition findings too.

Successful projects from Kaggle’s hundreds of competitions will likely continue to push boundaries in the field of data science.

7. Increased interest in consumer data protection

Consumer awareness about data privacy rose in the wake of the Cambridge Analytica scandal .

In fact, CIGI-Ipsos found that more than half of all consumers became more interested in data privacy in the year following the revelations.

Platforms like Facebook and Google, which previously harvested and shared user data freely, have since faced legal backlash and public scrutiny.

This broader data privacy trend means that large data sets will soon be walled off and harder to come by.

Businesses and data scientists will need to navigate legislation such as the California Consumer Privacy Act which came into effect at the start of 2020.

And this could become a bane for data science when it comes to the future acquisition and use of consumer data.

8. AI devs combating adversarial machine learning

Adversarial machine learning is where an attacker inputs data into a machine learning model with the aim of causing mistakes.

Essentially, it is an optical illusion designed for a machine.

Anti-surveillance clothing takes this approach to the masses.

They’re specifically designed to confuse face detection algorithms with bold shapes and patterns.

According to a Northeastern University study , this clothing can help prevent individuals' automated tracking via surveillance cameras.

Data scientists will need to defend against adversarial inputs like this. And provide trick examples for models to train on so as not to be fooled.

Adversarial training measures for models like this will become essential in the next decade.

Wrapping Up

Those are the 7 biggest data science trends over the next 3-4 years.

Data science, like any science, is changing by the day. From data governance to deepfake technology, the data science industry is set for some major shakeups.

Hopefully keeping tabs on these trends will help you stay one step ahead.

Using AgentM to watch for new research papers of interest

I’m getting enough of the pieces of AgentM in place that I’m able to get it to do useful things. I wrote a small program (ok AgentM wrote part of it) that fetches the last days worth of research papers from arxiv.org , filters them to the papers related to topics I care about, and then projects those filtered papers to a uniform markdown format for easy scanning:

It uses gpt-4o-mini so it’s cost effective to run and it took 6 or 7 minutes in total to process 553 papers. Here’s the meat of the code:

I did another pass other the 81 papers it selected as being on topic and had the model select the top 10 papers for the day using another projection:

This is pretty awesome! I am tempted to write the underlying library in python.

I setup a placeholder GitHub project and would happily add you as a contributor.

That would be awesome!

My git user is icdev2dev. Thanks !

This is what I was thinking about:

I was just chatting with a long time Microsoft colleague (we created the Microsoft Bot Framework together) and he’s excited to create a .NET version of AgentM.

We were discussing that achieving absolute parity across languages isn’t super critical because you really want to lean into the strengths and paradigms of each language. What feels natural to a JavaScript developer isn’t going to feel as natural to a Python developer and it’s definitely not going to feel natural to a .net developer.

The important part is to maintain the spirit of AgentM across languages. To that end I’ll leave it up to you and others to determine what that means for Python.

That’s right.

But as I am thinking more about it, I believe that we shou;d also build in failure tolerance into the framework.

For example, if I have shown a set of sentences (amongst many such sets) to the LLM for the purpose of doing some labeling on sentences,I don’t want to lose that showing if the (distributed) job suddenly fails in between. It should be able to restart for the remaining jobs, complete those and then return the function to the caller.

The semantics of the threads allows for this distibuted jobs to fail and be restarted, I think.

I believe that that might be also what openAI might be pursuing as well (long lived jobs).

Yeah that’s a good suggestion…

@icdev2dev I just finished getting AgentM to convert all of its JS code to Python and it actually didn’t do too bad of a job. It’s easily 80% of the way there.

It got paths to some of the components wrong because it assumed everything was relative and in the same folder but given that it could only see one file at a time I think it did a good job. I told it which libraries I wanted it to use and it followed all of that guidance:

I’ll check the generated code into the python repo shortly.

Long-Duration Energy Storage Can’t Wait

PNNL robotics, advanced instrumentation, and flow battery expertise to accelerate battery advances in new Energy Storage Research Alliance hub

Wei Wang is the Deputy Director of the Energy Storage Research Alliance (ESRA), which brings together world-class researchers from four national laboratories and 12 universities to enable next-generation battery and energy storage discovery.

The public wish list for battery makers is pretty straightforward. People want batteries that work for days without needing to be recharged, don’t leak or catch fire, and provide reliable energy storage for many years.

Our currently available energy storage technology meets those needs for several categories of batteries. But as a nation, the United States has an urgent unmet need for safe and reliable long-duration energy storage on a massive scale. Fulfilling that need will require new kinds of batteries capable of routinely providing energy to our electric grid and hauling heavy freight long distances.

The Energy Storage Research Alliance (ESRA) , a new Department of Energy (DOE) Energy Innovation hub, will meet those needs by accelerating the discovery of new battery materials and chemistries that use Earth-abundant components and  green manufacturing processes.

The ESRA hub, one of new two energy storage-focused hubs created by DOE, includes leadership from three national laboratories: Pacific Northwest National Laboratory (PNNL) , Lawrence Berkeley National Laboratory (Berkeley Lab), and Argonne National Laboratory, which serves as the hub’s headquarters. In addition, 12 universities will participate in ESRA research.

“The ESRA will provide a platform for us to deepen our fundamental research in cost-efficient battery materials and affordable technologies,” said PNNL’s Wei Wang , ESRA deputy director and director of PNNL’s Energy Storage Materials Initiative .

Now is the time

The DOE investment of up to $62.5 million over 5 years enables the ESRA hub to put into place the scientists, tools, and emerging technologies to rapidly identify the most promising science-based approaches to large-scale energy storage.

“In the last decade, our scientific understanding of how to store and release energy in chemical bonds has advanced dramatically,” said Wang. “Now is the time to accelerate that fundamental understanding of the materials, chemistries, and properties that show promise in long-duration energy storage. Working with our partners, PNNL will leverage its investments in redox flow battery technology, high-throughput robotics, nuclear magnetic resonance spectroscopy, and the scientific acumen of our people.”

Long-duration grid energy storage expertise

As our electric grid decarbonizes and comes to depend more and more on these intermittent energy sources, safe, dependable long-term energy storage becomes essential. PNNL battery experts have established scientific and technical prowess, and many patented advances, in one of the most promising ways to store intermittent energy: redox flow battery science.

Wang, a global leader in flow battery technology, and his PNNL colleagues are developing an accelerated approach to discovery of even more efficient and longer-lasting flow battery materials for grid applications. In 2023, his research team provided the first lab-scale demonstration of a flow battery working stably and reliably for more than a year.

Through ESRA, Wang and his colleagues plan to explore a vastly increased number of new battery materials and chemistries, coupled with artificial intelligence, to learn faster and eliminate dead ends and blind alleys in their search.

“The ESRA hub builds upon PNNL’s past projects and capabilities for fundamental science in energy storage, which have grown and matured with DOE Office of Science support,” said Karl Mueller , director of program development for Physical and Computational Sciences at PNNL.

A molecular digital twin

To speed their effort, the scientists will deploy two tireless colleagues that are always available for more experiments. Dubbed Albert and Beverly, these two custom-built units are part robot, part workstation, part intelligent database. These lab dynamos have already sped the PNNL team’s pace of new battery materials discovery. Now, PNNL scientists will take them to a new level, collaborating with Argonne’s artificial intelligence technologies. PNNL will also partner with scientists at Berkeley Lab who have a similar experimental system to look at solid-state batteries. The efforts will complement each other in the new ESRA hub, said Wang. Together, the team will be able to further accelerate material discovery and move to predictive material design through machine learning insights.

“We can use machine learning to correlate structures to their properties,” said Wang. “If the machine learning algorithm learns enough from those data, then the next time we modify a new structure or come up with a new structure, the algorithm would be able to predict with high fidelity whether that new structure would have properties of interest.”

In this way, the scientific team can quickly move on from unpromising materials and focus on more productive ideas and prototypes. This combination of the robotic workstation and the machine learning algorithms make a sort of science-based molecular digital twin. The concept of a digital twin is well known in manufacturing, where digital prototypes guide real-world industrial design and manufacturing. Here, the team will extend that concept to their scientific discovery work.

“We know that chemical synthesis and experimental testing are the most time- and labor-intensive steps,” said Wang. “The molecular digital twin will help us be more efficient with time and resources.”

In addition to the digital twin, PNNL has signature characterization tools that will be housed in PNNL’s Grid Storage Launchpad, a new facility dedicated for energy storage research that opened last month.  

Advanced nuclear magnetic resonance spectroscopy

Once a promising energy storage prototype is made, the research team will evaluate its ability to efficiently store energy, maintain its ability to charge and discharge, and be long-lasting. Researchers at PNNL have developed a unique facility, housed in PNNL’s Energy Sciences Center , to “watch” experimental energy storage systems in action. 

Dynamic nuclear polarization solid-state nuclear magnetic resonance allows scientists to obtain signals from a wider range of materials in a dynamic environment close to surfaces that are important for the movement of mass or charge in a battery. This capability, along with specialized sample chambers developed at PNNL, allows scientists to track the movement of ions—the energy carriers—as they move within a liquid. In addition, the scientists will watch liquids interacting with both positive and negative electrodes. These interfaces are where many battery systems run into problems. Understanding the dynamic there is a huge endeavor.

“One of the biggest challenges in understanding complex chemistries found in energy storage systems is being able to track movement of the energy carriers and how they interact with the other elements of the system,” said Vijay Murugesan , a PNNL materials science expert and scientific thrust lead of the new ESRA hub. “We have developed the scientific and technical capabilities to track these energy storage molecules in real time, using advanced nuclear magnetic resonance spectroscopy.”

Wang added, “Achieving ESRA goals requires a team science approach, and we are committed to moving forward not only to achieve scientific goals, but also to train the next generation of energy storage research scientists and engineers with diverse backgrounds. Our partnerships with 12 research universities will help us accomplish that goal.”

The Energy Storage Research Alliance (ESRA), a DOE Energy Innovation hub led by Argonne National Laboratory, brings together world-class researchers from four national laboratories and 12 universities to enable next-generation battery and energy storage discovery. ESRA will enable transformative discoveries in materials chemistry, gain a fundamental understanding of electrochemical phenomena, lay the scientific foundations for breakthroughs in energy storage technologies, and train a next-generation battery workforce to ensure U.S. scientific and economic leadership. 

Pacific Northwest National Laboratory draws on its distinguishing strengths in chemistry , Earth sciences , biology and data science to advance scientific knowledge and address challenges in sustainable energy and national security . Founded in 1965, PNNL is operated by Battelle for the Department of Energy’s Office of Science, which is the single largest supporter of basic research in the physical sciences in the United States. DOE’s Office of Science is working to address some of the most pressing challenges of our time. For more information, visit https://www.energy.gov/science/ .
