Global Surrogate Models

Global surrogates are really easy to understand, that’s an advantage of this method. First you build a black box model on the training data with the real labels. Then you let the model predict the labels for the same data and you build an interpretable model on the data with the predicted labels. Because the surrogate model is interpretable and build on the predictions of the black box model you learn how the black box model makes its prediction.
