Witryna4 mar 2011 · The expectation maximization algorithm has been classically used to find the maximum likelihood estimates of parameters in probabilistic models with unobserved data, for instance, mixture models. A key issue in such problems is the choice of the model complexity. The higher the number of components in the mixture, the higher … WitrynaNewton method yields feasible convergence time Using ICA/IVA mixture model allows implementation of Newton method without matrix inversions (2x2 block diagonal Hessian) 10 Convergence Rates Convergence is really much faster than natural gradient. Works with step size 1!
