Figure 4From: A maximum likelihood framework for protein designModel comparison. Cross-validation (CV) scores obtained for the different forms of potentials tested. The average gain (relative to the CV score obtained with the flat potential μ, see Methods) for the 2-fold cross-validation experiment is reported. α14ac: solvent accessibility potential, 14 accessibility classes; ε: contact potential; MJ: Miyazawa and Jernigan's potential.Back to article page
