Hierarchical Optimal Transport for Multimodal Distribution Alignment

WebIn this work, we propose a hierarchical optimal transport (HOT) method to mitigate the dependency on these two assumptions. Given unaligned multi-view data, the HOT method penalizes the sliced Wasserstein distance between the distributions of different views.
