WebJul 11, 2024 · Expectation Maximization (EM) is a classic algorithm developed in the 60s and 70s with diverse applications. It can be used as an unsupervised clustering algorithm … In statistics, an expectation–maximization (EM) algorithm is an iterative method to find (local) maximum likelihood or maximum a posteriori (MAP) estimates of parameters in statistical models, where the model depends on unobserved latent variables. The EM iteration alternates between performing an … See more The EM algorithm was explained and given its name in a classic 1977 paper by Arthur Dempster, Nan Laird, and Donald Rubin. They pointed out that the method had been "proposed many times in special circumstances" by … See more Although an EM iteration does increase the observed data (i.e., marginal) likelihood function, no guarantee exists that the sequence converges to a maximum likelihood estimator. For multimodal distributions, this means that an EM algorithm … See more EM is frequently used for parameter estimation of mixed models, notably in quantitative genetics. In See more The EM algorithm is used to find (local) maximum likelihood parameters of a statistical model in cases where the equations cannot be solved directly. Typically these … See more The symbols Given the statistical model which generates a set $${\displaystyle \mathbf {X} }$$ of observed data, a set of unobserved latent data or See more Expectation-Maximization works to improve $${\displaystyle Q({\boldsymbol {\theta }}\mid {\boldsymbol {\theta }}^{(t)})}$$ rather … See more A Kalman filter is typically used for on-line state estimation and a minimum-variance smoother may be employed for off-line or batch state … See more
