Data mining allows you to search for information and behavior patterns in large databases. Weka is an application developed for this purpose with something to its favor in comparison with other similar programs: it is developed using the GNU General Public License and it is free of charge.
Take on data mining on your PC
Weka has been developed in Java by the University of Waikato in New Zealand, and its name is due to a flightless bird that can be found in this country. These algorithms can be applied straight to a database or they can be called from their own Java code.
The application includes tools to process the data, classify it, for regressions, for clustering, for association rules or for visualization. It is also perfectly prepared for the development of new learning schemes for machines.
Forget about pay-to-use options to carry out data mining. Download Weka to your PC for free and start working with large amounts of information.
