ANN based Genome Classifier using Frequency Chaos Game Representation

Abstract—Classification of organisms into different categories using their genomic sequences has found its importance in the study of evolutionary characteristics of organisms and specific identification of previously unknown organisms in bio-diversity studies and related areas. Chaos game representation (CGR) uniquely represents DNA sequence in a visual format and reveals hidden patterns in it. Frequency CGR (FCGR) derived from CGR shows the frequency of sub-sequences present in the DNA sequence. In this paper, a novel method for classification of organisms based on a combination of FCGR and Artificial Neural network (ANN) is proposed. Eight categories, from the taxonomical distribution of Eukaryotic organisms are taken from NCBI and ANN is used for classification. Different con- figurations of ANN are tested and good accuracy is obtained. The way, the fractal nature of CGR helps in classification, is also investigated.

Index Terms—Artificial Neural Network, frequency chaos game representation, genome classification, mitochondrial genomes.
