Hello,it is my pleasure to announce the DecisionTree package. It provides an implementation of the ID3 algorithm [1] and can be used to classify data with discrete valued attributes.
You can get it from* hackage: http://hackage.haskell.org/cgi-bin/hackage-scripts/package/ DecisionTree * my own webspace: http://page.mi.fu-berlin.de/aneumann/decisiontree/ DecisionTree-0.0.tar.gz
At this stage it is very likely buggy and slow, as I don't have a sufficiently large dataset to test with.
You are encouraged to have a look at the source, it is quite short and well commented. Please feel free to make suggestions, send in patches or point me to some dataset I could use for testing.
Regards, Adrian
