New method estimates Gaussian Mixture Models with unknown covariances

Researchers have developed a new method for estimating Gaussian Mixture Models (GMMs) with unknown diagonal covariances. This approach utilizes the Beurling-LASSO (BLASSO) convex optimization framework to simultaneously determine the number of components and their parameters. The method offers enhanced flexibility compared to prior techniques by accommodating component-specific, unknown diagonal covariance matrices and provides theoretical guarantees for parameter recovery and density prediction.
