Dataset Generator (Dat Gen)
http://www.datasetgenerator.com
One important way to test learning-from-example algorithms is
to evaluate their performance against well understood synthetic
data sets. The Dat Gen program (formerly known as Synthetic Classification Data Sets - SCDS) generates synthetic data sets which are particularly useful to test Knowledge Discovery from Database (KDD) algorithms.
