Localized Temporal Reasoning: A State-Based Approach
We are concerned with temporalreasoning problems where there is uncertainty about the order in which events occur. The task of temporal reasoning is to derive an event sequence co...

On Equivalence Between Network Topologies
One major open problem in network coding is to characterize the capacity region of a general multi-source multi-demand network. There are some existing computational tools for boun...

Self-Validated Labeling of Markov Random Fields for Image Segmentation
—This paper addresses the problem of self-validated labeling of Markov random fields (MRFs), namely to optimize an MRF with unknown number of labels. We present graduated graph c...
