This paper demonstrates a conceptually simple but effective method of increasing the accuracy of QA systems on factoid-style questions. We define the notion of an inverted questio...
—This paper describes a new three-dimensional spatiotemporal template, namely the Volumetric Motion History Image (VMHI), for the purpose of human motion analysis. Irregularities...
The idea of risk permeates the information security field. We use terms like ``risk management'', ``risk assessment'', ``risk model'' and ``risk analy...
We propose a novel unsupervised learning framework for activity perception. To understand activities in complicated scenes from visual data, we propose a hierarchical Bayesian mod...
There are two major approaches to activity coordination in multiagent systems. First, by endowing the agents with the capability to jointly plan, that is, to jointly generate hypot...
