Abstract

The main contribution of this paper is to propose a novel EM algorithm that utilizes ideas of EM algorithm and maximum-entropy uniform distribution to find a stable optimum in an uncomplicated way. The conventional EM algorithms may suffer from the following two problems: first, it may converge to an undetermined local maximum; second, the algorithm may suffer from singularity. The novel EM algorithm is deterministic that the solution is determined solely by the initial condition. In our novel EM algorithm, a stable and optimal solution can be obtained by using a uniform distribution instead of special initial condition. In addition, a positive perturbation scheme is adopted to avoid singularity. Experimental results have demonstrated that the novel EM is uncomplicated and effective for stable optimum compared with some prior arts.
