SORES
Searching Optimal Rough Entropy Sets

Ivo Düntsch and Günther Gediga

These pages contain the details of the computations presented in the paper Uncertainty measures of rough set prediction. An extended abstract, Feature selection and data prediction by rough entropy , is also available.
For each of the data sets we have looked at, we provide the detailed SORES results, a pointer to the original data, and a zipped file with the used - possibly discretized - data in the Grobian format:

foo0.ris - Rough filtered data
foo1.ris - At most 10 classes in the continuous attributes
foo2.ris - At most 5 classes in the continuous attributes

The decision attribute is the last one, unless otherwise indicated. A utility to convert (and discretize) the original data to Grobian format, is available from the Grobian home page .
