# 50 Must-Read Free Books For Every Data Scientist in 2020

**By Reashikaa Verma, ParellelDots**

Data science is an inter-disciplinary field which contains methods and techniques from fields like statistics, machine learning, Bayesian etc. They all aim to generate specific insights from the data. In this article, we are listing down some excellent data science books which cover the wide variety of topics under Data Science.

### 1. The Element of Data Analytic Style

This book gives an overview of Data Science. Data Science is a very large umbrella term and this book is good for anyone trying to get their feet wet in the field for the first time. Read it to understand what Data Science is, what are some general tasks and algorithms, and some general tips and tricks.

### 2. Foundations of Data Science

Foundations of Data Science is a treatise on selected fields that form the basis of Data Science like Linear Algebra, LDA, Markov Chains, Machine Learning basics, and statistics. The ideal readers for the book are the beginner data scientists wanting to make their mathematical and theoretical grasp on the field better.

### 3. Mining of Massive Datasets

Based on Stanford courses CS246 and CS35A, the book helps users learn topics to do Data Mining on large datasets. Often a very common problem a data scientist has to solve is to perform simple numerical tasks (which you can do by writing small pieces of programs) on a very large dataset. MMDS works exactly towards that. Added to that, you have topics like Dimensionality Reduction and Recommendation Systems which help you learn about the application of linear algebra and metric distances in the real world. An absolute must-read for all Data Scientists.

### 4. Python Data Science Handbook

Python Data Science Handbook teaches the application of various Data Science concepts in Python. Probably the best book to learn Data Science in Python ( only equivalent is Wes McKinney’s mouse book), this book is also free to read on Github. So you can learn without spending any money.

### 5. Hands-on Machine Learning and Big Data

### 6. Think Stats

Think Stats teaches readers the basics of statistics, that is, readers will apply statistical concepts and distributions on real-world datasets and try to learn more about data using mathematical characteristics. Probably one of the best books to get started with if you want to learn statistics with Python.

### 7. Think Bayes

Bayesian Statistics works somewhat differently from normal statistics. The concepts of uncertainty and fitting distributions to real-world datasets make Bayesian methods more fitting to learn about real-world datasets. Prof. Downey’s extremely cool “learn by programming it in Python” style makes the book a treat for those getting started with Bayesian Methods.

### 8. Introduction to Linear Dynamical Systems

This book teaches applied Linear Algebra in real-world systems. The applications involve circuits, signal processing, communications, and control systems. Link to previous years’ course notes by professor Boyd can be found here.

### 9. Convex Optimization

Convex Optimization is what many Machine Learning (and almost all Deep Learning algorithms) algorithms use in the background to arrive at the optimal set of parameters.

### 10. Essentials of Metaheuristics

Metaheuristics are quick learning probabilistic ways to do tasks that would require you to otherwise write programs to search using Brute Force. For maybe small data, Brute Force approaches take lesser effort to implement, but they exhaust very fast with the amount of data added. This book is probably the best introduction to metaheuristic methods like Genetic Algorithms, Hill Climbing, Co-Evolution, and (basic) Reinforcement Learning.

### 11. Machine Learning in Python: Main Developments and Technology Trends in Data Science, Machine Learning, and Artificial Intelligence

A good overview of Python tools in data Science. A very good document for a senior Python developer wanting to get into Data Science or someone moving into Python from R for Data Science. Overall if you want to understand what Python can do for Data Science, you should read this article.

### 12. Applied Data Science

Applied Data Science by Langmore and Krasner is a book that takes a very practical approach to teach Data Science. From using Git, teaching Basic Python, the book goes on to build fundamentals of various algorithms that are used frequently in the field of Data Science.

### 13. Bandit Book

With more and more data getting accumulated, decision making is no more a function of intuition but a function of collected data. What is the right color of a buy button on an e-commerce website to drug testing and financial portfolio decisions, bandit algorithms are used everywhere? A very good book to make oneself acquainted with “banditry”!

### 14. Annotated Algorithms

A book that teaches you to code many numerical algorithms in Python. An excellent resource if you want to learn how mathematical programs are implemented or want to learn Python with interesting problem statements.

### 15. Computer Age Statistical Inference

A book by Efron and legendary Hastie thinking how Statistical Inference (both frequentist and bayesian) should be done in modern times using the computational power available nowadays rather than the pen-and-paper approach most other books take. This is a must-read by anyone (beginner or experienced) who intends to use Statistics in real life.

### 16. Causal Inference Book

“Correlation is not causation” is a phrase that Data Scientists use a lot. But how to separate the two? This book provides answers by describing causal inference techniques to Data Scientists. You will need good probability basics to read it, not for total beginners.

### 17. Computational Optimal Transport

Optimal Transport is the mathematics of assignment from one set of distributions into another. This is probably one of the few fields in Data Science that has won more than one Fields Medals (the highest honor in Mathematics). The mathematical concepts are used in many Machine Learning and Deep Learning algorithms as distance metrics and for assignment problem-solving.

### 18. Algebra, Topology, Differential Calculus and Optimization Theory for Computer Science and Machine Learning

The book aims to teach various mathematical fields required in Computer Science and Machine Learning. Quite Mathematical and a good resource for those who want to come into Data Science from Maths heavy fields.

### 19. Data Mining and Analysis

Data Mining, as you might have seen in the more famous MMDS book mentioned earlier, is a method to do computations effectively on a large dataset. These computations can be done by brute force methods, and might work well on small datasets, but might take really really long to run on large datasets. A good introductory and reference book for Data Mining.

### 20. Computational and Inferential Thinking

Looks into various aspects of Data Science from programming in Python, Causality, Tables, Visualization and basic statistics. From a basic course at UC Berkeley, so a good resource for beginners.

### 21. Mathematical Foundations of Data Science

As the name suggests, the book gives and explains mathematical treatise behind Data Science concepts like Convex Optimization and Dimensionality Reduction. This book is recommended if you like Mathematics or are specifically looking to learn Maths behind these concepts.

### 22. Information Theory for Intelligent People

Information theory is one of the four mathematical theories you will find in Data Science along with Linear Algebra, Convex Optimization, and Statistics. This is a good tutorial to understand the theory. The good thing is that the tutorial is accessible to beginners.

### 23. Introduction to Applied Linear Algebra – The VMLS Book

My favorite Linear Algebra book out of the many I will mention in this list. It is accessible to beginners and has a very applied feeling to it, not making the reader lose themselves in a lot of mathematical concepts.

### 24. Linear Algebra – Hefferon

Many people believe it to be the best beginner Linear algebra resources available after Strong’s Bible. Also very applied, (programming exercises in SAGE, which is basically Python) but more for beginners than practitioners.

### 25. Linear Algebra – As An Introduction to Abstract Mathematics

This book feels like my college linear algebra book (which was loved by many students who studied engineering with me). I get a bit lost when there is too much Math and slightly lesser applications, but a lot many would enjoy the elegance of such books.

### 26. Fundamentals of Linear Algebra and Optimizations

This book combines Linear Algebra with Optimization algorithms. Again, more Math oriented books for people who like the style.

### 27. Linear Algebra Lecture Notes – Lerner

I found it really good, it’s like showing you multiple solved problems to make you learn. Not as much rigor as earlier books and more learning-by-showing. Good refresher for people who have not touched Linear Algebra for a long time.

### 28. Lecture Notes on Randomized Linear Algebra

Not everyone will need to read the book as it deals with probabilistic algorithms to solve Linear Algebra problems. Useful if you work on large matrices and vectors, where simple algorithms will not work.

### 29. Linear Algebra via Exterior Products

A very different way to look at Linear Algebra. If you find Linear Algebra cool, you should try visualizing problems in this new way.

### 30. Linear Algebra – Cherney et al

Another free book for college-level Linear Algebra. Good for beginners. It also comes with homework problems if you want to practice.

### 31. Matrix Calculus you need for Deep Learning

As the name suggests, the tutorial helps you understand the Matrix Calculus you require for Deep Learning.

### 32. Optimization: An Introduction

Optimizing parameters is required in problems across Engineering fields. While Convex Optimization is used in many Deep Learning algorithms, knowing about other algorithms like Linear Programming, Simplex broadens one’s horizons.

### 33. Scipy Lecture Notes

If you are going to work in Data Science, you will need to learn the scientific Python stack. Probably the best common tutorial to learn Numpy, Scipy, Scikit-Learn, Scikit-Image and all the libraries you need.

### 34. Pandas Mega Tutorial

This huge tutorial is by the Pandas development team to learn and understand the library. Pandas is a must-learn library if you are working in Data Science. There is no escape.

### 35. Kalman and Bayesian Filters in Python

Kalman Filters and other Bayesian Filters are useful when working with noisy data coming with time which can be fitted to a certain model with parameters to be deduced. The twofold thing these models do is deduce the parameters as well as model the noise. Though most commonly used examples are location data, similar filters can work things well in forecasting too. (Also available at Github)

### 36. Statistical Inference for Data Science

We have looked at multiple Statistical Inference books before this, but this one is written especially keeping Data Scientists in mind. If you are a Data Scientist, trying to get a quick handle on statistical inference, this is your book.

### 37. Mathematics for Machine Learning

A detailed book teaching you Mathematics needed to make sense of most of the Machine Learning Algorithms out there. Beginner’s friendly.

Information Theory and Inference are generally dealt with differently, but late Prof. MacKay’s book tries to tackle both the subjects.

### 47. Scientific Improvement of Decision Making and Risk Management

A not too technical tutorial around probabilistic decision making.

### 48. Thirty-three Miniatures: Mathematical and Algorithmic Applications of Linear Algebra

This is not really a book on Linear Algebra, but rather a few cool applications of Linear Algebra compiled into a book.

### 49. A Genetic Algorithm Tutorial

Genetic Algorithms are tools that all Data Scientists need to use sometime in their life. This tutorial helps beginners understand how Genetic Algorithms work.

### 50. Computing in Operations Research using Julia
