WebHierarchical Optimal Transport for Multimodal Distribution Alignment: Reviewer 1. Post-rebuttal update: The authors' response is very thorough and clarifies many of my concerns, mostly those due to what it seems was a misunderstanding of what their baselines were (due to inexact/missing explanations). WebIn this paper, we propose a principled notion of distance between histopathology datasets based on a hierarchical generalization of optimal transport distances. Our method does not require any training, is agnostic to model type, and preserves much of the hierarchical structure in histopathology datasets imposed by tiling.
