Cutoff for exact recovery of Gaussian mixture models

Xiaohui Chen, Yun Yang

We determine the information-theoretic cutoff value on separation of cluster centers for exact recovery of cluster labels in a K-component Gaussian mixture model with equal clust…

Diffusion K-means clustering on manifolds: provable exact recovery via semidefinite relaxations

Xiaohui Chen, Yun Yang

We introduce the {\it diffusion K-means} clustering method on Riemannian submanifolds, which maximizes the within-cluster connectedness based on the diffusion distance. The diffu…

Hanson-Wright inequality in Hilbert spaces with application to K-means clustering for non-Euclidean data

Xiaohui Chen, Yun Yang

We derive a dimension-free Hanson-Wright inequality for quadratic forms of independent sub-gaussian random variables in a separable Hilbert space. Our inequality is an infinite-dim…
