Recognizing Linked Events: Searching the Space of Feasible Explanations
The ambiguity inherent in a localized analysis of events from video can be resolved by exploiting constraints between events and examining only feasible global explanations. We sho...

Information Flow Security in Dynamic Contexts
We study a security property for processes in dynamic contexts, i.e., contexts that can be reconfigured at runtime. The security property that we propose in this paper, named Per...

Substate tying with combined parameter training and reduction in tied-mixture HMM design
Two approaches are proposed for the design of tied-mixture hidden Markov models (TMHMM). One approach improves parameter sharing via partial tying of TMHMM states. To facilitate ty...

Doubly Robust Smoothing of Dynamical Processes via Outlier Sparsity Constraints
Abstract—Coping with outliers contaminating dynamical processes is of major importance in various applications because mismatches from nominal models are not uncommon in practice...
