Scheme of computer algorithm based on pattern recognition theory. Signs – amino acid pairs chosen from different positions within an epitope sequence . Dipi – discrimination parameter equal to total number of epitope specific “signs” found at learning step. sP – “space pairs” - amino acid pairs separated in a peptide by one, two, three amino acids . QsP - is the quality of sP which is defined by the occurrence of the particular sP in all epitope mimotopes at learning.
