# JDataAnalysis
Author: Roodschild Matías
[email protected]

## Introduction

This project was created with the idea to facilitate handling of data for machine learning. Its design goals are; 1) to be accessible to both novices and experts, and 2) facilitate data manipulation algorithms. JDataAnalysis is free, written in 100% Java and has been released under Apache v2.0 license.

Currently JDataAnalysis supports:

* CSV Files (open, and extract features by columns)

## Documentation

Not yet available


## Dependencies
-----------------------------------------

The main JDataAnalysis modules depends on the following libraries

- [ EJML ] ( http://code.google.com/p/efficient-java-matrix-library )
- [ Apache Commons-csv ] ( https://commons.apache.org/proper/commons-csv/ )
- [ j-text-utils ] ( https://github.com/Udinic/j-text-utils/tree/master/repo/dnl/utils/j-text-utils )

The following is required for unit tests

- [ JUnit ] ( http://junit.sourceforge.net/ )
