International audience.We consider the Mixture of Experts (MoE) modeling for clustering heterogeneous regression data with possibly high-dimensional features and propose a regularized maximum-likelihood estimation based on a dedicated EM algorithm which integrates coordinate ascent updates of the parameters. Unlike state-of-the art regularized MLE for MoE, the proposed modeling does not require an approximate of the regularization. Theproposed algorithm allows to automatically obtaining sparse solutions without thresholding, and includes coordinate ascent updates avoiding matrix inversion, and can thus be scalable. An experimental study shows the good performance of the algorithm in terms of recovering sparse solutions, density estimation, ...
