Towards a Game-Theoretic View of Baseline Values in the Shapley Value

no code implementations29 Sep 2021 Jie Ren, Zhanpeng Zhou, Qirui Chen, Quanshi Zhang

In the computation of Shapley values, people usually set an input variable to its baseline value to represent the absence of this variable.

Can We Faithfully Represent Masked States to Compute Shapley Values on a DNN?

1 code implementation22 May 2021 Jie Ren, Zhanpeng Zhou, Qirui Chen, Quanshi Zhang

Masking some input variables of a deep neural network (DNN) and computing output changes on the masked input sample represent a typical way to compute attributions of input variables in the sample.
