Principle component analysis (PCA) scores plot of the distribution of AVPs and Non-AVPs, where AVPs and Non-AVPs are represented by red and blue circles, respectively. (a) and (c) represent the distribution of amino acid composition and a new feature representation, respectively, obtained from the dataset T^544p+407n + V^60p+45n, while (b) and (d) represent the distribution of pseudo amino acid composition and a new feature representation, respectively, obtained from the dataset T^544p+544n + V^60p+60n.
