WebHausdorff Distance Masks is a new method developed for the interpretability of image segmentation models. Like RISE, it is a black box method. The output of the method has a higher resolution than RISE and is more accurate. How does it work? ¶ The first part of the algorithm is the occlusion of parts of the input image. Web1. Projections: Every image of a polytope Punder an a ne map is a polytope. 2. Intersections: Every intersection of a polytope with an a ne subspace is a polytope. However, the computational step from one of the main theorem’s descriptions of polytopes to the other a \convex hull computation" is often far from trivial.
