A public-domain software package for the interactive visual exploration of multivariate data sets. It is available on all UNIX platforms which support XR4 or higher. The current version of the software (3.1) supports scatterplots, star glyphs, paralle...

Platform- and data-source-independent library for embedded data mining based on the CWM/OMG and other data mining standards. XELOPES-Java algorithms: SVMs, market basket analysis, sequence analysis, decision trees, cluster analysis, multidimensional g...

By David Chickering at Microsoft Research. The WinMine Toolkit is a set of tools for Windows 2000/NT/XP that allow you to build statistical models from data. The majority of the tools are command-line executables that can be run in scripts.

Windows software tool that induces rules using the PNC2 cluster algorithm. An integrated parameter tuning component allows an easy adjustment of the algorithm's behaviour to the given problem without any further knowledge. [Gnu GPL]

Environment for statistical computing and dynamic graphics based on Lisp. Contains contributed code and submission instructions.

Modelling tool that analyzes data generating classification, regression or class probability prediction models.

Open Source creation of a data mining C++ procedure library. Initially focused on mining generalised association rules and generalised sequential patterns

A freely available software toolkit for finding frequent patterns in diverse datasets. It contains highly efficient algorithms for finding patterns in transactional, sequential, and graph datasets.

GPL C/C++ software for data analysis of discrete data using principal/independent component methods. Examples are DPCA, LDA, GaP (like PLSI and NMF). Targetted at text, with MPI and multithreading.

Model based clustering and discriminant analysis, including hierarchical clustering and EM. Developed at University of Washington.
