Learning to Classify Species with Barcodes

ABSTRACT
According to many field experts, species identification based on morphological keys needs to be supported with automated techinques based on the analysis of DNA fragments (referred to as ''barcode''). The most successful results in this area are those obtained from a particular fragment of mithocondrial DNA, the gene cytochrome c oxidase I (COI). We present the results obtained on a dataset where a number of COI fragments composed of $690$ LOCI are used to describe 1700 individuals belonging to 150 different species. The method proposed exhibits high correct recognition rate on a 20% testing set (correct recognition approx. 99%$when 30 features are used). It is able to provide compact formulas on the values (A,C,G,T) at the selected loci that synthetize the characteristic of each specie, a quite precious information for many tasks of interest for taxonomists.
