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.

Optimization

Solutions to some problems are not as cut and dry as correct or incorrect, but are rated in terms of quality. Such problems are known as optimization problems because the goal is to find the candidate solution with the best, that is, optimal quality.

What is a fitness function?

SwarmOps works for real-valued and single-objective optimization problems, that is, optimization problems that map candidate solutions from -dimensional real-valued spaces to one-dimensional real-valued spaces. Mathematically speaking, we consider optimization problems to be functions of the following form:

In SwarmOps, it is assumed that is a minimization problem, meaning that we are searching for the candidate solution with the smallest...
