WebNov 5, 2024 · Notes on Optimal Transport. This summer, I stumbled upon the optimal transportation problem, an optimization paradigm where the goal is to transform one probability distribution into another with a minimal cost. It is so simple to understand, yet it has a mind-boggling number of applications in probability, computer vision, machine … WebThe learned attention matrices are also dense and lacks interpretability. We propose Graph Optimal Transport (GOT), a principled framework that germinates from recent advances in Optimal Transport (OT). In GOT, cross-domain alignment is formulated as a graph matching problem, by representing entities into a dynamically-constructed graph.
