Real World AI - elements of AI Introduction

This course includes six chapters, starting with an introduction to AI, moving through problem solving, real-world AI, ML, Neural Nets and more. Each chapter is made up of several exercises which will test your understanding of the theoretical learning. You can read more on the course here.  

Natural Language Processing with Coursera

This course covers a wide range of tasks in Natural Language Processing from basic to advanced: sentiment analysis, summarization, dialogue state tracking, to name a few. Upon completing, you will be able to recognize NLP tasks in your day-to-day work, propose approaches, and judge what techniques are likely to work well.  The final project is devoted to one of the most hot topics in today’s NLP. View more on the course here.

Free e-books covering AI

Think Stats - Probability and Statistics for Programmers

Allen B. Downey

Think Stats emphasizes simple techniques you can use to explore real data sets and answer interesting questions. The book presents a case study using data from the National Institutes of Health. Readers are encouraged to work on a project with real datasets. You can access your free copy here.

A Programmer's Guide to Data Mining

Ron Zacharski

This guide follows a learn-by-doing approach. Instead of passively reading the book, Ron encourages you to work through the exercises and experiment with the Python code provided. The textbook is laid out as a series of small steps that build on each other until, by the time you complete the book, you have laid the foundation for understanding data mining techniques. You can see more on the textbook here.

Foundations of Programming Languages

Kent D Lee

This clearly written textbook provides an accessible introduction to the three programming paradigms of object-oriented/imperative, functional, and logic programming. Highly interactive in style, the text encourages learning through practice, offering test exercises for each topic covered. You can see more information on this textbook from Kent Lee here.

A Brief Introduction to Neural Networks

David Kriesel

This eBook is available in both English and German, covering 5 parts, starting with the history and realization of Neural Models and ending with Unsupervised learning Network Paradigms. Read more on the content of this eBook here. You can also download your free version in pdf format here.

Artificial Intelligence: Foundations of Computational Agents, 2nd Edition

David L. Poole and   Alan K. Mackworth

Over sixteen chapters, David and Alan cover supervised machine learning, multiagent systems, planning and certainty and more. This eBook is free to view but if used, please consider buying the works to support the authors. You can read more on the foundations of AI here.

A Beginner’s Guide to R

Alain F. ZuurElena N. IenoErik H. W. G. Meesters

Based on their extensive experience with teaching R and statistics to applied scientists, the authors provide a beginner's guide to R. To avoid the difficulty of teaching R and statistics at the same time, statistical methods are kept to a minimum. The text covers how to download and install R, import and manage data, elementary plotting, an introduction to functions, advanced plotting, and common beginner mistakes. This book contains everything you need to know to get started with R. You can access your free copy here.

Reinforcement Learning - An Introduction

Richard Sutton & Andrew Barto

Richard and Andrew list their goal in writing this book was to provide a clear and simple account of the key ideas and algorithms of reinforcement learning. Both authors wanted their treatment to be accessible to readers in all of the related disciplines. For the most part, our treatment takes the point of view of artificial intelligence and engineering. read the PDF copy here.

Methods of Mathematical Modelling

Thomas Witelski & Mark Bowen

This book presents mathematical modelling and the integrated process of formulating sets of equations to describe real-world problems. Thomas and Mark describe methods in this book for obtaining solutions of challenging differential equations stemming from problems in areas such as chemical reactions, population dynamics, mechanical systems, and fluid mechanics. Access this book via the springer website here.

Learning OpenCV 3: Computer Vision in C++ with the OpenCV Library

Adrian Kaehler & Gary Bradski

Learning OpenCV is a great addition to the list, focussed on Computer Vision in C++ with the OpenCV Library, introducing computer vision and demonstrating how you can quickly build applications that enable computers to see and make decisions based on that data. It is thoroughly updated to cover new features and changes in OpenCV 3.0. See more on this book here.
