Duality in Graphical Models
Dhafer Malouche, Bala Rajaratnam, Benjamin T. Rolfs
Graphical models have proven to be powerful tools for representing high-dimensional systems of random variables. One example of such a model is the undirected graph, in which lack…
Iterative Thresholding Algorithm for Sparse Inverse Covariance Estimation
Dominique Guillot, Bala Rajaratnam, Benjamin T. Rolfs +2
The L1-regularized maximum likelihood estimation problem has recently become a topic of great interest within the machine learning, statistics, and optimization communities as a me…
A note on the lack of symmetry in the graphical lasso
Benjamin T. Rolfs, Bala Rajaratnam
The graphical lasso (glasso) is a widely-used fast algorithm for estimating sparse inverse covariance matrices. The glasso solves an L1 penalized maximum likelihood problem and is…
Low temperature thermal resistance for a new design of silver sinter heat exchanger
J. Pollanen, H. Choi, J. P. Davis +2
We have developed a novel procedure for constructing high surface area silver sinter heat exchangers. Our recipe incorporates nylon fibers having a diameter of ~ 50 microns and thi…
