Abstract

Computational intelligence is an ongoing area of research, which has been successfully utilized in the analysis and modeling of the tremendous amount of biological data accumulated under different high throughput genome sequencing projects. The data gathered is mainly comprised of DNA, RNA and protein sequences, which are imprecise, incomplete and increasing exponentially. Classification of protein sequences into different superfamilies could be helpful for knowing the structure/function or hidden characteristics of an unknown protein sequence. The problem of classifying protein sequences based on the primary sequence information is a very complex and challenging task in the analysis and understanding of sequenced data. The existing classification methods are performing well on a very limited data; however the rapid increase in the genomic data leads to the development of improved computational methods. In this work, we have proposed an optimized tree-classification technique which uses cluster k nearest neighbor classification algorithm to classify protein sequences into superfamilies. The proposed technique is alignment free and the experimental results reveal that it outperforms than the previous state-of-the-art approaches. The overall best classification accuracy achieved is 97-98 on the previously utilized dataset, which is taken from the well-known UniProtKB database. © 2015 IEEE.
