The robust EM-type algorithms for log-concave mixtures of regression models
COMPUTATIONAL STATISTICS & DATA ANALYSIS, 111, 14–26.
author keywords: EM algorithm; Log-concave Maximum Likelihood Estimator; Mixture of regression model; Robust regression
TL;DR:
A new method is proposed to estimate the mixture regression parameters by only assuming that the components have log-concave error densities but the specific parametric family is unknown, which has comparable performance to the normal EM algorithm.

Maximum likelihood estimation of the mixture of log-concave densities
COMPUTATIONAL STATISTICS & DATA ANALYSIS, 101, 137–147.
author keywords: Consistency; Log-concave maximum likelihood estimator (LCMLE); Mixture model
TL;DR:
This paper considers a much more flexible mixture model, which assumes each component density to be log-concave, and shows that the LCMLE improves the clustering results while comparing with the traditional MLE for parametric mixture models.
