Abstract

This paper presents a combination of Combined Multiple Models (CMM) technique and evolutionary approach that is used for tuning of multiple parameters. Proposed hybrid classifier was tested in microarray gene expression analysis domain. This domain was chosen intentionally, because of the nature of Combined Multiple Models classifiers that are specialized in solving problems with high dimensionality and contain low number of samples. Evolutionary tuning of parameters in combination with validation dataset enables fine tuning of parameters that are usually set to pre-defined values. Using this technique another step in leveling the accuracy of comprehensible classifiers to those represented by ensembles of classifiers was made.
