Webb8 dec. 2024 · the Naive Shapley method is based on the alternative intuition of measuring a feature’s impact in relation to it being absent from the model altogether during training. And so the contribution of “Age=30” in our example would be relative to the case of the model being initially trained with no Age feature at all. Webb3.
