Semiparametric Estimation of Symmetric Mixture Models with Monotone and Log-Concave Densities
Xiao Pu, Ery Arias-Castro
In this article, we revisit the problem of fitting a mixture model under the assumption that the mixture components are symmetric and log-concave. To this end, we first study the n…

A Simple Approach to Sparse Clustering
Ery Arias-Castro, Xiao Pu
Consider the problem of sparse clustering, where it is assumed that only a subset of the features are useful for clustering purposes. In the framework of the COSA method of Friedma…
