Likelihood Maximization and Moment Matching in Low SNR Gaussian Mixture Models

Anya Katsevich, Afonso Bandeira

We derive an asymptotic expansion for the log likelihood of Gaussian mixture models (GMMs) with equal covariance matrices in the low signal-to-noise regime. The expansion reveals a…

Analysis of a fourth order exponential PDE arising from a crystal surface jump process with Metropolis-type transition rates

Yuan Gao, Anya E. Katsevich, Jian-Guo Liu +2

We analytically and numerically study a fourth order PDE modeling rough crystal surface diffusion on the macroscopic level. We discuss existence of solutions globally in time and l…
