Abstract

The classification of human gene sequences into exons and introns is an important but difficult problem. We study the discriminative power of various statistical features (22 in total) in term of their mutual information (MI). By performing correlation analysis, we are able to identify a set of features that has high MI value while at the same time is complementary in their information content. Using the set of features, which consists of the three SZ features, the AMI feature, and the first stop codon feature, we are able to achieve classification accuracy as high as 92%.
