Learning Overspecified Gaussian Mixtures Exponentially Fast with the EM Algorithm
Zhenisbek Assylbekov, Alan Legg, Artur Pak
We investigate the convergence properties of the EM algorithm when applied to overspecified Gaussian mixture models -- that is, when the number of components in the fitted model ex…
