Confusion matrix for classification models: A) training set for three-class model; B) test set for three-class model; C) training set for binary model; D) test set for binary model.

(Alt Text): Four confusion matrices describing the performance of training and testing sets for two classification models. While three classes model was unable to estimate the mAbs with medium solubility in test set accurately, binary model had high predictability in both training and testing set.
