This book is an exploration of neural networks and how to implement them in Java. First, the reader is guided so as to understand what neural networks are. You will learn how they operate. The process of learning in neural networks is very important. This is the concept which makes neural networks behave in the same manner as the brain of human beings. This process is discussed in this book. You are also guided on how to implement this in Java. The Java lego robots are very common in the field of artificial intelligence. This book guides you on how to implement these in Java. Recurrent neural networks, which are believed to have memory, are discussed in detail. These work in such a way that the value will be calculated based on the value obtained in the previous step. You will learn how to implement such a network in Java. Convolutional neural networks are also explored in detail. You will learn how these work as well as how to implement them in Java.The following topics are discussed in this book:-Understanding Neural Networks-Learning in Neural Networks-Java Lego Robots Neural Network-Convolutional Neural Networks-Recurrent Neural Networks
