Gradient EM needs $\sqrt{d}$ separation for Gaussian mixtures in high dimensions
A new paper explores the necessity of component separation for gradient EM algorithms to learn Gaussian mixture models in high dimensions. The research demonstrates that a separation of order $\Omega(d^{0.5-\epsilon})$ …

Gradient EM algorithm achieves global convergence for over-parameterized Gaussian Mixtures
Researchers have established a global convergence guarantee for the gradient Expectation-Maximization (EM) algorithm when applied to over-parameterized Gaussian Mixture Models (GMMs). This marks the first such result fo…
