Researchers have developed a new Sample-Sketch-Solve paradigm to optimize the runtime for estimating Wasserstein distances between probability distributions. This method uses a regular grid sketch to compress data, which aids in faster computation while maintaining accuracy. The approach achieves an optimal or near-optimal runtime for certain smooth distributions, particularly in lower dimensions. AI
