Weka is a collection of machine learning algorithms for solving real-world data mining problems. It is written in Java and runs on almost any platform. The algorithms can either be applied directly to a dataset or called from your own Java code.


Weka is a free machine learning software which was developed at the University of Waikato in New Zealand. You would want to use this software for analysing the data and predictive modeling because it contains algorithms and visualization tools that support machine learning. It was written in Java programming language and it has a GUI that provides an easy and simple access to the features.

Weka allows you to do big data mining tasks like mining, processing, visualization, regression and so on based on the assumption that data is in the form of a flat file.
