Detection of period-3 behavior in genomic sequences using singular value decomposition

Abstract

Manydigital signal processing techniques have beenusedtoautomatically distinguish theprotein coding regions (exons) fromnon-coding regions (introns) inaDNAsequence. Recently, Auto-regressive (AR) technique hasbeenused forthedetection of3periodicty present inprotein coding regions of genomic sequences. The. sequence length, average spacing between coding regions, andaverage coding region length arethemainfactors thataffect the performance ofanyprediction method Inthis paper, wepropose theuseofSingular Value Decomposition (SVD) methodfor thedetection ofperiod-3 behavior in DNA sequences. Results showthatSVDmethod outperforms theARtechnique.
