New research links MLE and control variates in machine learning algorithms

Researchers have established a theoretical equivalence between Maximum Likelihood Estimation (MLE) and Control Variate Estimators (CVE) within sketching algorithms for machine learning. This equivalence, demonstrated under specific conditions in an exponential family, suggests that an optimal CVE can achieve the same asymptotic variance as an MLE, thereby enabling a fixed-point algorithm for MLE. Experimental results indicate this fixed-point approach offers improved speed and numerical stability compared to traditional root-finding methods for MLE, particularly for bivariate normal distributions.
