Research on the residue-residue contacts in interactive proteins ismeaningful in determining the function and structure of proteins, structure-baseddrug design, and disease treatment. Previous methods showed good predictedresults, however, the number of false positive non-residue-residue contacts (nonRRCs) is still much higher than the number of true positive residue-residuecontacts (RRCs). In this research, we propose a method to eliminate false positivenon-RRCs enhancing the predicted quality. The experimental results showed thatour proposed method to increase the predicted quality in some cases
