Kokot, Murad, and Meila (2025) · The Noisy Laplacian: a threshold phenomenon for non-linear dimension reduction

A study of the effect of noise in common dimension reduction algorithms, and the geometry recoverable in these settings. To appear at ICML. Preprint

Kokot et al. (2025) · The EGOP Flow: Local features for Continuous Index Learning

We study a local kernel method motivated by local advances related to the EGOP. We show that under a supervised noisy manifold hypothesis, it is possible to learn functions at intrinsic dimensional rates under a suitable Wasserstein flow. Preprint
