Deep Learning: Practical Neural Networks with Java

Loading/selecting data

First we need to load raw data into our Java environment. Data can be stored in a variety of data sources, from text files to structured database systems. One basic and simple type used is CSV (Comma-Separated Values), which is simple and in general use. In addition, we'll need to transform this data and perform selection before presenting it to the neural network.

Building auxiliary classes

To deal with these tasks, we need some auxiliary classes in the package edu.packt.neuralnet.data. The first will be LoadCsv to read CSV files:

public class LoadCsv { //Path and file name separated for compatibility private String PATH; private String FILE_NAME; private double[][] dataMatrix; private boolean columnsInFirstRow=false; private ...
