Abstract EN
Within the learning framework of maximum weighted likelihood (MWL) proposed by Cheung, 2004 and 2005, this paper will develop a batch Rival Penalized Expectation-Maximization (RPEM) algorithm for density mixture clustering provided that all observations are available before the learning process.
Compared to the adaptive RPEM algorithm in Cheung, 2004 and 2005, this batch RPEM need not assign the learning rate analogous to the Expectation-Maximization (EM) algorithm (Dempster et al., 1977), but still preserves the capability of automatic model selection.
Further, the convergence speed of this batch RPEM is faster than the EM and the adaptive RPEM in general.
The experiments show the superior performance of the proposed algorithm on the synthetic data and color image segmentation.
