Correlation plot of the experimental and predicted binding affinities by the MLR (left) and RF (right) general scoring functions. Models trained on the PDBbind v2013 refined set (N = 2764) and evaluated on curated v2013 core set (N = 195). R is the Pearson’s correlation coefficient and RMSE is the root mean squared error given in kcal mol−1.
