Sensitivity and specificity of amino acid encodings after cross-validation. (1) encoding providing the best sensitivity ($\mathrm{AUC}=0.9683$, $\mathrm{MCC}=0.8677$), (2) encoding providing the best specificity ($\mathrm{AUC}=0.9338$, $\mathrm{MCC}=0.6474$). These encodings are shown in Table 2 and Table 3, respectively.
