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 visualizations

In this section we will go over some of the many that you will see in our program. This includes both two and three dimensional plots.

Understanding two-dimensional visualizations

For our application, we have several two-dimensional visualizations that we need to explain. The first is the two-dimensional plot of the function optimization, be it maximized or minimized. This visualization is shown as follows. Remember, for this we are using Microsoft Chart control, which is available from: https://www.microsoft.com/en-us/download/details.aspx?id=14422:

2D Visualization

For each particle that we are plotting (up to a maximum of 10), we will have a different marker style. A marker is the diamonds...
