Experimental results for biological activity prediction of glycogen synthase kinase-3 β inhibitors. The categorical attributes were ranked based on their estimated conditional entropies. We chose the first 31 attributes with smallest entropy values for problem partition. We restructured the learning problem according to these candidate attributes separately, and built linear models for each partition. Among the 31 attributes, there are 17 categorical attributes whose performance beat the baseline approach in terms of both cross-validation accuracy and test accuracy.
