Feature attribution methods identify which features of an input most influence a model’s output. Most widely-used feature attribution methods (such as SHAP, LIME, and Grad-CAM) are “class-dependent” methods in that they generate a feature attribution vector as a function of class. In this work, we d…
Although Shapley values are theoretically appealing for explaining black-box models, they are costly to calculate and thus impractical in settings that involve large, high-dimensional models. To remedy this issue, we introduce FastSHAP, a new method for estimating Shapley values in a single forward…
While the need for interpretable machine learning has been established, many common approaches are slow, lack fidelity, or hard to evaluate. Amortized explanation methods reduce the cost of providing interpretations by learning a global selector model that returns feature importances for a single in…
