The MM Alternative to EM

Parameter Convergence for Em and Mm Algorithms

It is well known that the likelihood sequence of the EM algorithm is nondecreasing and convergent (Dempster, Laird and Rubin (1977)), and that the limit points of the EM algorithm are stationary points of the likelihood (Wu (1982)), but the issue of the convergence of the EM sequence itself has not been completely settled. In this paper we close this gap and show that under general, simple, ver...

EM vs MM: A case study

The celebrated expectation-maximization (EM) algorithm is one of the most widely used optimization methods in statistics. In recent years it has been realized that EM algorithm is a special case of the more general minorization-maximization (MM) principle. Both algorithms creates a surrogate function in the first (E or M) step that is maximized in the second M step. This two step process always...

The health system approach to the complementary and alternative medicine

Since different nations have emphasized reusing their traditional methods in medicine over the last two decades, and the World Health Organization’s recent approach has also focused on restoring traditional medicine in different parts of the world, those methods that are more compatible with the popular culture of a country should be considered. In our country, the traditional medicine, with it...

from linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar

chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
