7 free books and manuals on data science

Today, 23 April, is World Book Day, an occasion to highlight the importance of reading, writing and the dissemination of knowledge. Active reading promotes the acquisition of skills and critical thinking by bringing us closer to specialised and detailed information on any subject that interests us, including the world of data. 

Therefore, we would like to take this opportunity to showcase some examples of books and manuals regarding data and related technologies that can be found on the web for free. 

1. Fundamentals of Data Science with R, edited by Gema Fernandez-Avilés and José María Montero (2024) 

Access the book here.

• What is it about? The book guides the reader from the problem statement to the completion of the report containing the solution to the problem. It explains some thirty data science techniques in the fields of modelling, qualitative data analysis, discrimination, supervised and unsupervised machine learning, etc. It includes more than a dozen use cases in sectors as diverse as medicine, journalism, fashion and climate change, among others. All this, with a strong emphasis on ethics and the promotion of reproducibility of analyses. 
• Who is it aimed at? It is aimed at users who want to get started in data science. It starts with basic questions, such as what is data science, and includes short sections with simple explanations of probability, statistical inference or sampling, for those readers unfamiliar with these issues. It also includes replicable examples for practice. 
• Language: Spanish.  

2. Telling stories with data, Rohan Alexander (2023). 

Access the book here.

• What is it about? The book explains a wide range of topics related to statistical communication and data modelling and analysis. It covers the various operations from data collection, cleaning and preparation to the use of statistical models to analyse the data, with particular emphasis on the need to draw conclusions and write about the results obtained. Like the previous book, it also focuses on ethics and reproducibility of results. 
• Who is it aimed at? It is ideal for students and entry-level users, equipping them with the skills to effectively conduct and communicate a data science exercise. It includes extensive code examples for replication and activities to be carried out as evaluation. 
• Language: English. 

3. The Big Book of Small Python Projects, Al Sweigart (2021) 

Access the book here.

• What is it about? It is a collection of simple Python projects to learn how to create digital art, games, animations, numerical tools, etc. through a hands-on approach. Each of its 81 chapters independently explains a simple step-by-step project - limited to a maximum of 256 lines of code. It includes a sample run of the output of each programme, source code and customisation suggestions. 
• Who is it aimed at?  The book is written for two groups of people. On the one hand, those who have already learned the basics of Python, but are still not sure how to write programs on their own.  On the other hand, those who are new to programming, but are adventurous, enthusiastic and want to learn as they go along. However, the same author has other resources for beginners to learn basic concepts. 
• Language: English. 

4. Mathematics for Machine Learning, Marc Peter Deisenroth A. Aldo Faisal Cheng Soon Ong (2024) 

Access the book here.

• What is it about?  Most books on machine learning focus on machine learning algorithms and methodologies, and assume that the reader is proficient in mathematics and statistics. This book foregrounds the mathematical foundations of the basic concepts behind machine learning 
• Who is it aimed at? The author assumes that the reader has mathematical knowledge commonly learned in high school mathematics and physics subjects, such as derivatives and integrals or geometric vectors. Thereafter, the remaining concepts are explained in detail, but in an academic style, in order to be precise. 
• Language: English. 

5. Dive into Deep Learning, Aston Zhang, Zack C. Lipton, Mu Li, Alex J. Smola (2021, continually updated) 

Access the book here.

• What is it about? The authors are Amazon employees who use the mXNet library to teach Deep Learning. It aims to make deep learning accessible, teaching basic concepts, context and code in a practical way through examples and exercises. The book is divided into three parts: introductory concepts, deep learning techniques and advanced topics focusing on real systems and applications. 
• Who is it aimed at?  This book is aimed at students (undergraduate and postgraduate), engineers and researchers, who are looking for a solid grasp of the practical techniques of deep learning. Each concept is explained from scratch, so no prior knowledge of deep or machine learning is required. However, knowledge of basic mathematics and programming is necessary, including linear algebra, calculus, probability and Python programming. 
• Language: English. 

6. Artificial intelligence and the public sector: challenges, limits and means, Eduardo Gamero and Francisco L. Lopez (2024) 

Access the book here.

• What is it about? This book focuses on analysing the challenges and opportunities presented by the use of artificial intelligence in the public sector, especially when used to support decision-making. It begins by explaining what artificial intelligence is and what its applications in the public sector are, and then moves on to its legal framework, the means available for its implementation and aspects linked to organisation and governance. 
• Who is it aimed at? It is a useful book for all those interested in the subject, but especially for policy makers, public workers and legal practitioners involved in the application of AI in the public sector. 
• Language: Spanish 

7. A Business Analyst’s Introduction to Business Analytics, Adam Fleischhacker (2024) 

Access the book here.

• What is it about? The book covers a complete business analytics workflow, including data manipulation, data visualisation, modelling business problems, translating graphical models into code and presenting results to stakeholders. The aim is to learn how to drive change within an organisation through data-driven knowledge, interpretable models and persuasive visualisations. 
• Who is it aimed at? According to the author, the content is accessible to everyone, including beginners in analytical work. The book does not assume any knowledge of the programming language, but provides an introduction to R, RStudio and the "tidyverse", a series of open source packages for data science. 
• Language: English.
