Convex Graph Invariants
Venkat Chandrasekaran, Pablo A. Parrilo, Alan S. Willsky
The structural properties of graphs are usually characterized in terms of invariants, which are functions of graphs that do not depend on the labeling of the nodes. In this paper w…
The Convex Geometry of Linear Inverse Problems
Venkat Chandrasekaran, Benjamin Recht, Pablo A. Parrilo +1
In applications throughout science and engineering one is often faced with the challenge of solving an ill-posed inverse problem, where the number of available measurements is smal…
Latent variable graphical model selection via convex optimization
Venkat Chandrasekaran, Pablo A. Parrilo, Alan S. Willsky
Suppose we observe samples of a subset of a collection of random variables. No additional information is provided about the number of latent variables, nor of the relationship betw…
