Space-Alternating Generalized Expectation-Maximization Algorithm
The expectation-maximization (EM) method can facilitate maximizing likelihood functions that arise in statistical estimation problems. In the classical EM paradigm, one iteratively maximizes the conditional log-likelihood of a single unobservable complete data space, rather than maximizing the intractable likelihood function for the measured or incomplete data. EM algorithms update all paramete...

متن کاملThe Expectation-Maximization and Alternating Minimization Algorithms
The Expectation-Maximization (EM) algorithm is a hill-climbing approach to finding a local maximum of a likelihood function [7, 8]. The EM algorithm alternates between finding a greatest lower bound to the likelihood function (the “E Step”), and then maximizing this bound (the “M Step”). The EM algorithm belongs to a broader class of alternating minimization algorithms [6], which includes the A...
متن کاملNoise Benefits in Expectation-Maximization Algorithms
This dissertation shows that careful injection of noise into sample data can substantially speed up Expectation-Maximization algorithms. Expectation-Maximization algorithms are a class of iterative algorithms for extracting maximum likelihood estimates from corrupted or incomplete data. The convergence speed-up is an example of a noise benefit or"stochastic resonance"in statistical signal proce...
