Abstract

The microarray can be used to measure the changes in the expression levels of thousands of genes simultaneously, to detect SNPs or to genotype or resequence mutant genomes. The high dimensional feature vectors of microarray impose a high dimensional cost as well as the risk of overfitting during classification. Feature selection is one way of reducing the dimensionality. Effective feature selection can be done based on correlation between attributes. In this paper, we introduce a correlation based wrapper algorithm for feature selection using genetic algorithm (GA) and Support Vector Machines with kernel functions for classification. We compare our approach with existing algorithm.
