Generating Post-hoc Counterfactuals and the Risk of Out-of-distribution Explanations 

Get Complete Project Material File(s) Now! » From Counterfactual Reasoning to Counterfactual Explanations in Machine Learning Counterfactual reasoning. The term counterfactual originally comes from psychology (see e.g. Roese, 1997; Byrne, 2008), and Artificial Intelligence literatures (Lewis, 1973; Ginsberg, 1986). In...

Comparison of the predictive distributions associated with the estimators (MLE and MAP) and the full posterior distribution
