Webb2 maj 2024 · Accordingly, models were derived to account for all 103 human kinases for which inhibitors were available. Each output neuron provided a binary classification output. Rationalizing predictions of multi-kinase activity of inhibitors was of special interest. MT-DNN predictions were interpretable using the model-independent kernel SHAP approach. WebbHere we introduced an additional index i to emphasize that we compute a shap value for each predictor and each instance in a set to be explained.This allows us to check the accuracy of the SHAP estimate.
