Efficient Transferable Optimal Transport via Min-Sliced Transport Plans
Researchers have introduced the min-Sliced Transport Plan (min-STP) framework to address the computational cost of Optimal Transport (OT) in computer vision tasks. This new approach optimizes a one-dimensional projection to create a conditional transport plan, significantly reducing computation time. The study also investigates the transferability of these optimized slicers to new distribution pairs, finding that they remain effective even with slight data perturbations, enabling efficient transfer across related tasks and amortized training for applications like point cloud alignment and generative modeling.
