Deep Learning Illustrated is a visual, interactive introduction to artificial intelligence published in 2019 by Pearson’s Addison-Wesley imprint.

It became an instant #1 Bestseller in several Amazon categories, including Neural Networks and Data Mining.

A summary of the book is available via Medium, and all of the code featured in the book is available open-source in GitHub.

Physical copies of Deep Learning Illustrated can be ordered worldwide through, e.g., Amazon, Barnes & Noble. Digital versions are also available via, e.g., InformIT, Amazon Kindle, and Safari Books. If you order via this InformIT link and use the code KROHN during checkout, you get 35% off both physical and digital versions.

Deep learning is transforming software, facilitating powerful new artificial intelligence capabilities, and driving unprecedented algorithm performance. Deep Learning Illustrated is uniquely intuitive and offers a complete introduction to the discipline’s techniques. Packed with full-color figures and easy-to-follow code, it sweeps away the complexity of building deep learning models, making the subject approachable and fun to learn.

World-class instructor and practitioner Jon Krohn—with visionary content from Grant Beyleveld and beautiful illustrations by Aglaé Bassens—presents straightforward analogies to explain what deep learning is, why it has become so popular, and how it relates to other machine learning approaches. Krohn has created a practical reference and tutorial for developers, data scientists, researchers, analysts, and students who want to start applying it. He illuminates theory with hands-on Python code in accompanying Jupyter notebooks. To help you progress quickly, he focuses on the versatile deep learning library Keras to nimbly construct efficient TensorFlow models; PyTorch, the leading alternative library, is also covered.

You’ll gain a pragmatic understanding of all major deep learning approaches and their uses in applications ranging from machine vision and natural language processing to image generation and game-playing algorithms.
