Researchers have developed a new method called streaming sliced Wasserstein (Stream-SW) to estimate the sliced Wasserstein (SW) distance from data streams. This approach enhances computational scalability by introducing a streaming estimator for the one-dimensional Wasserstein distance (1DW), which is then applied to all projections to create Stream-SW. The method offers low memory complexity while providing theoretical guarantees on approximation error, outperforming random subsampling in experiments with Gaussian distributions and mixtures. Stream-SW has also shown favorable performance in applications like point cloud classification, gradient flows, and change point detection. AI
