Frontostriatal Fiber Bundle Compromise in HIV Infection Without Dementia
Quantitative fiber tracking derived from diffusion tensor imaging (DTI) was used to determine whether white matter association, projection, or commissural tracts are affected in nondemented individuals with HIV infection and to identify…

Action Exemplar Based Real-Time Action Detection
We propose a real-time action detection system based on a novel action representation and an effective learning method with a small training set. We represent actions with a new feature…

Does Session Variability Compensation in Speaker Recognition Model Intrinsic Variation Under Mismatched Conditions?
We find that ISV compensation is remarkably successful on a corpus of intrinsic variation that is highly controlled for channel (a dominant component of ISV). The results are particularly surprising…
