Proceedings ArticleDOI
Sparse representations for automatic target classification in SAR images
Jayaraman J. Thiagarajan,Karthikeyan Natesan Ramamurthy,Peter Knee,Andreas Spanias,Visar Berisha +4 more
TL;DR: Results show that the performance of the algorithm is superior to using a support vector machines based approach with similar assumptions, and significant complexity reduction is obtained by reducing the dimensions of the data using random projections for only a small loss in performance.
Journal ArticleDOI
Empirically Estimable Classification Bounds Based on a Nonparametric Divergence Measure
TL;DR: It is shown that a nonparametric f-divergence measure can be used to provide improved bounds on the minimum binary classification probability of error for the case when the training and test data are drawn from the same distribution.
Journal ArticleDOI
Persistent post-traumatic headache vs. migraine: an MRI study demonstrating differences in brain structure
Todd J. Schwedt,Catherine D. Chong,Catherine D. Chong,Jacob Peplinski,Katherine B. Ross,Visar Berisha +5 more
TL;DR: Differences in regional volumes, cortical thickness, surface area and brain curvature were identified when comparing the group of individuals with persistent post-traumatic headache to the group with migraine, suggesting differences in their underlying pathophysiology.
Journal ArticleDOI
Tracking discourse complexity preceding Alzheimer's disease diagnosis: a case study comparing the press conferences of Presidents Ronald Reagan and George Herbert Walker Bush.
TL;DR: A method to extract key features from discourse transcripts from President Ronald Reagan and President George Herbert Walker Bush, who have no known diagnosis of Alzheimer's disease, were described and regression analyses were conducted.
Journal ArticleDOI
Automatic assessment of vowel space area.
TL;DR: An automated algorithm is described using healthy, connected speech rather than single syllables and estimates the entire vowel working space rather than corner vowels, revealing a strong correlation between the traditional VSA and automated estimates.
