Age detection on Qin et al. dataset using Pfam, KEGG pathway and KEGG Ontology. Age detection using (a) Pfam (b) KEGG pathway and (c) KEGG Ontology on Qin et al. dataset show that classification performance increases towards mid-age cutoffs. TF-iDF appears to be a more accurate and consistent feature selection method for age detection compared to mRMR. KEGG, Kyoto Encyclopedia of Genes and Genomes; mRMR, minimum-redundancy maximum-relevancy; Pfam, protein family; TF-iDF, term frequency-inverse document frequency.
