Abnormal event detection based on trajectory clustering by 2-depth greedy search
Clustering-based approaches for abnormal video event detection have been proven to be effective in the recent literature. Based on the framework proposed in our previous work [1],...

An instantaneous vector representation of delta pitch for speaker-change prediction in conversational dialogue systems
As spoken dialogue systems become deployed in increasingly complex domains, they face rising demands on the naturalness of interaction. We focus on system responsiveness, aiming t...

How Bad is Suboptimal Rate Allocation?
Abstract—Not too bad. A rate allocation that is suboptimal with respect to a utility maximization formulation still maintains the maximum flow-level stability when the utility g...
