Abstract

The gene expression dataset generated by DNA microarray technology contains expression profiles of huge quantities of genes for very small samples. Among these genes, a very small number of genes are informative for cancer sample identification and classification. Informative genes finding is an essential task of microarray gene expression data analysis. Here, a new hybrid gene selection-sample classification model (NHGSSC) is proposed for selection of relevant genes and classification of cancer samples. The NHGSSC performs two tasks-gene selection and sample classification. For gene selection, a new hybrid single filter and α-depth limited best first search based single wrapper method (SFα-BFSSW) is proposed. From these subsets, highly informative genes are selected by counting frequency of occurrence (FO) of every gene. Then SFα-BFSSW method-based ensemble classifier (SFα-BFSSWEC) is built by combining the classifiers created for the selected gene subsets. Experimental results demonstrate the superiority of the NHGSSC to other existing models.
