Fig. 2From: Protein-protein interaction prediction using a hybrid feature representation and a stacked generalization schemeVectorial representations of two proteins, P1 and P2. a Each amino acid AAi is first translated into a vector of 14 physicochemical scale values, b Both proteins, P1 and P2, are later represented in a uniform vectorial form with 28 AC values. We demonstrate the calculation of the first two AC values of H11 for P2 when the gap is 1 (g = 1) and 2 (g = 2), respectivelyBack to article page
