Importance of different feature types to the improvement of cleavage site prediction performance for eight proteases. The height of each bar for a feature type represents the proportional ‘contribution percentage’ that represents the AUC value of the feature selection model for one protease, and the uniformed AUC drop rate for each type of feature is represented with different colors. The AUC drop rate was obtained by comparing with the model after removing this feature from the input.
