Concentration of kernel matrices with application to kernel spectral clustering

no code implementations7 Sep 2019 Arash A. Amini, Zahra S. Razaee

We derive nonasymptotic exponential concentration inequalities for Lipschitz kernels assuming that the data points are independent draws from a class of multivariate distributions on $\mathbb R^d$, including the strongly log-concave distributions under affine transformations.

2 code implementations21 Mar 2019 Arash A. Amini, Marina Paez, Lizhen Lin, Zahra S. Razaee

We propose an exact slice sampler for Hierarchical Dirichlet process (HDP) and its associated mixture models (Teh et al., 2006).
