Distributed Estimation, Information Loss and Exponential Families
Qiang Liu, Alexander Ihler
Distributed learning of probabilistic models from multiple data repositories with minimum communication is increasingly important. We study a simple communication-efficient learnin…
Marginal Structured SVM with Hidden Variables
Wei Ping, Qiang Liu, Alexander Ihler
In this work, we propose the marginal structured SVM (MSSVM) for structured prediction with hidden variables. MSSVM properly accounts for the uncertainty of hidden variables, and c…
Variational Algorithms for Marginal MAP
Qiang Liu, Alexander Ihler
The marginal maximum a posteriori probability (MAP) estimation problem, which calculates the mode of the marginal posterior distribution of a subset of variables with the remaining…
Planar Cycle Covering Graphs
Julian Yarkony, Alexander T. Ihler, Charless C. Fowlkes
We describe a new variational lower-bound on the minimum energy configuration of a planar binary Markov Random Field (MRF). Our method is based on adding auxiliary nodes to every f…
