[data mining] Magnum Opus Demo

The exciting new tool for finding associations -- if-then rules that highlight interrelationships among attributes. A free ten-day evaluation will convince you that Magnum Opus is the best association rule software available!

I did try it. It is easy to use. List file format is simple.
The output is understandable. The free trial version is good enough for data mining study.

[freeware] WEKA: Data Mining Free Software

Weka is a collection of machine learning algorithms for data mining tasks.The algorithms can either be applied directly to a dataset or called from your own Java code. Weka contains tools for data pre-processing, classification, regression, clustering, association rules, and visualization. It is also well-suited for developing new machine learning schemes.
