Book description
With the resurgence of neural networks in the 2010s, deep learning has become essential for machine learning practitioners and even many software engineers. This book provides a comprehensive introduction for data scientists and software engineers with machine learning experience. You’ll start with deep learning basics and move quickly to the details of important advanced architectures, implementing everything from scratch along the way.
Author Seth Weidman shows you how neural networks work using a first principles approach. You’ll learn how to apply multilayer neural networks, convolutional neural networks, and recurrent neural networks from the ground up. With a thorough understanding of how neural networks work mathematically, computationally, and conceptually, you’ll be set up for success on all future deep learning projects.
This book provides:
 Extremely clear and thorough mental models—accompanied by working code examples and mathematical explanations—for understanding neural networks
 Methods for implementing multilayer neural networks from scratch, using an easytounderstand objectoriented framework
 Working implementations and clearcut explanations of convolutional and recurrent neural networks
 Implementation of these neural network concepts using the popular PyTorch framework
