Hands-On Neural Network Programming with C#

By: Matt Cole

Overview of this book

Neural networks have made a surprise comeback in the last few years and have brought tremendous innovation in the world of artificial intelligence. The goal of this book is to provide C# programmers with practical guidance in solving complex computational challenges using neural networks and C# libraries such as CNTK, and TensorFlowSharp. This book will take you on a step-by-step practical journey, covering everything from the mathematical and theoretical aspects of neural networks, to building your own deep neural networks into your applications with the C# and .NET frameworks. This book begins by giving you a quick refresher of neural networks. You will learn how to build a neural network from scratch using packages such as Encog, Aforge, and Accord. You will learn about various concepts and techniques, such as deep networks, perceptrons, optimization algorithms, convolutional networks, and autoencoders. You will learn ways to add intelligent features to your .NET apps, such as facial and motion detection, object detection and labeling, language understanding, knowledge, and intelligent search. Throughout this book, you will be working on interesting demonstrations that will make it easier to implement complex neural networks in your enterprise applications.

Understanding GRUs

GRUs are a cousin to the long short-term memory recurrent neural networks. Both LSTM and GRU networks have additional parameters that control when and how their internal memory is updated. Both can capture long- and short-term dependencies in sequences. The GRU networks, however, involve less parameters than their LSTM cousins, and as a result, are faster to train. The GRU learns how to use its reset and forget gates in order to make longer term predictions while enforcing memory protection. Let's look at a simple diagram of a GRU:
