Summary Extinction coefficient (EC), as the key parameter of target intensity model, is assumed constant in classical infrared target tracking (IRTT) methods. The derivation below shows why the EM algorithm using this “alternating” updates actually works. I need an unscented / kalman filter forecast of a time series. Contribute to MarkDaoust/mvn development by creating an account on GitHub. EM solves a Maximum Likelihood problem of the form: µ: parameters of the probabilistic model we try to find x: unobserved variables z: observed variables ... EM for Extended Kalman Filter Setting . So the basic idea behind Expectation Maximization (EM) is simply to start with a guess for \(\theta\), then calculate \(z\), then update \(\theta\) using this new value for \(z\), and repeat till convergence.
