Researchers have developed new methods to make Gromov-Wasserstein (GW) distances more scalable and computationally efficient. One approach, min Generalized Sliced Gromov-Wasserstein (min-GSGW), uses generalized slicers to learn compatible mappings for heterogeneous datasets, enabling geometric matching and shape analysis at a lower cost. Another method, Sliced Inner Product Gromov-Wasserstein Distances, addresses the GW problem with inner product costs, offering a scalable solution with rotational invariance that has been applied to text clustering and language model representation comparison.
