Coreset selection for the Sinkhorn divergence and generic smooth divergences arXiv:2504.20194v1 Announce Type: new Abstract: We introduce CO2, an efficient algorithm to produce convexly-weighted coresets with respect to generic smooth divergences. By employing a functional Taylor expansion, we show a local equivalence between sufficiently regular losses and their second order approximations, reducing the coreset selection…
