Neural networks and deep learning: book, free, online, visual, AI

Neural networks and deep learning
"Neural Networks and Deep Learning is a free online book.
The book will teach you about:

• Neural networks, a beautiful biologically-inspired programming paradigm which enables a computer to learn from observational data
• Deep learning, a powerful set of techniques for learning in neural networks

Neural networks and deep learning currently provide the best solutions to many problems in image recognition, speech recognition, and natural language processing. This book will teach you many of the core concepts behind neural networks and deep learning."
