Abstract: A statistical learning framework is presented for multiple mixed graphical models via a penalized approximate likelihood estimation. We describe a fast algorithm for variational maximum likelihood inference, which takes advantage of the log-determinant relaxation. We identify a necessary and sufficient condition to discover the connected components in the solution. We then employ a divide-and-conquer approach to the joint structural inference problem for multiple related large sparse networks.
