Recoverability Landscape of Tree Structured Markov Random Fields under Symmetric Noise
Ashish Katiyar, Soumya Basu, Vatsal Shah +1
We study the problem of learning tree-structured Markov random fields (MRF) on discrete random variables with common support when the observations are corrupted by a -ary symmet…
Robust Estimation of Tree Structured Ising Models
Ashish Katiyar, Vatsal Shah, Constantine Caramanis
We consider the task of learning Ising models when the signs of different random variables are flipped independently with possibly unequal, unknown probabilities. In this paper, we…
Robust estimation of tree structured Gaussian Graphical Model
Ashish Katiyar, Jessica Hoffmann, Constantine Caramanis
Consider jointly Gaussian random variables whose conditional independence structure is specified by a graphical model. If we observe realizations of the variables, we can compute t…
