Web12 Dec 2007 · Abstract. We consider the problem of estimating sparse graphs by a lasso penalty applied to the inverse covariance matrix. Using a coordinate descent procedure for the lasso, we develop a simple algorithm—the graphical lasso—that is remarkably fast: It solves a 1000-node problem (∼500000 parameters) in at most a minute and is 30–4000 … WebKeywords--2 x 2 block matrix, Inverse matrix, Structured matrix. 1.
