Neural Network Programming with Java

By: Alan M. F. Souza, Fabio M. Soares

Overview of this book

<p>Vast quantities of data are produced every second. In this context, neural networks become a powerful technique to extract useful knowledge from large amounts of raw, seemingly unrelated data. One of the most preferred languages for neural network programming is Java as it is easier to write code using it, and most of the most popular neural network packages around already exist for Java. This makes it a versatile programming language for neural networks.</p> <p>This book gives you a complete walkthrough of the process of developing basic to advanced practical examples based on neural networks with Java.</p> <p>You will first learn the basics of neural networks and their process of learning. We then focus on what Perceptrons are and their features. Next, you will implement self-organizing maps using the concepts you’ve learned. Furthermore, you will learn about some of the applications that are presented in this book such as weather forecasting, disease diagnosis, customer profiling, and characters recognition (OCR). Finally, you will learn methods to optimize and adapt neural networks in real time.</p> <p>All the examples generated in the book are provided in the form of illustrative source code, which merges object-oriented programming (OOP) concepts and neural network features to enhance your learning experience.</p>

Download and install NetBeans

Tip

Before downloading and installing NetBeans, make sure that you have installed the JDK (Java Development Kit), which can be downloaded from https://www.oracle.com/java/index.html.

Follow these steps to download and install NetBeans:

  1. NetBeans can be freely downloaded at the project's site https://netbeans.org/downloads/index.html (shown in the following figure); choose the installer that is to be downloaded according to your operation system, as shown in the drop-down list platform:

  2. You can select from the versions displayed in the web page. For the projects in this book, the Java SE version fits very well; in addition, it is the smallest and lightest version as well. The download should start shortly; in every case, you can click on the download it here button, as shown in the following screenshot:

  3. After the download, you should run the netbeans-<version>-javase-<your_os>.exe executable file. The following screen appears. You can perform the standard installation then. When executing the installer, it tells you about the size of the installation and the version. You can then click on the Next button.

  4. You must accept the license agreement by marking the checkbox, as shown in the following screenshot, and then click on the Next button:

  5. Then, you can select the folders where the program will be installed or you can just leave the default folders, as indicated in the following screenshot:

  6. Now, we're ready to install. You may the click on the Check for Updates checkbox and just click on the Install button.

  7. After the installation, you may click on the NetBeans icon on the desktop to run NetBeans. An initial page will open:
