An empirical comparative study of approximate methods for binary graphical models; application to the search of associations among causes of death in French death certificates
Vivian Viallon, Onureena Banerjee, Gregoire Rey +2
Looking for associations among multiple variables is a topical issue in statistics due to the increasing amount of data encountered in biology, medicine and many other domains invo…
First-order methods for sparse covariance selection
Alexandre d'Aspremont, Onureena Banerjee, Laurent El Ghaoui
Given a sample covariance matrix, we solve a maximum likelihood problem penalized by the number of nonzero coefficients in the inverse covariance matrix. Our objective is to find a…
Sparse Covariance Selection via Robust Maximum Likelihood Estimation
Onureena Banerjee, Alexandre d'Aspremont, Laurent El Ghaoui
We address a problem of covariance selection, where we seek a trade-off between a high likelihood against the number of non-zero elements in the inverse covariance matrix. We solve…
