Smooth Reparameterizations of Functions on Simplicial Product Spaces: Applications to Probabilistic Tensor Decomposition and Functional Data Registration
Shashwat Kumar, Arafat Rahman, Anuj Srivastava +1
We consider optimization problems defined on product spaces of simplices. Examples of this class of problems include learning low-rank discrete multivariate probability distributio…
An Elastic Shape Variational Autoencoder for Skeleton Pose Trajectories
Arafat Rahman, Shashwat Kumar, Laura E. Barnes +1
Deep generative models provide flexible frameworks for modeling complex, structured data such as images, videos, 3D objects, and texts. However, when applied to sequences of human…
SocialPulse: An On-Smartwatch System for Detecting Real-World Social Interactions
Md Sabbir Ahmed, Arafat Rahman, Mark Rucker +1
Social interactions are a fundamental part of daily life and play a critical role in well-being. As emerging technologies offer opportunities to unobtrusively monitor behavior, the…
Fairness in Machine Learning-based Hand Load Estimation: A Case Study on Load Carriage Tasks
Arafat Rahman, Sol Lim, Seokhyun Chung
Predicting external hand load from sensor data is essential for ergonomic exposure assessments, as obtaining this information typically requires direct observation or supplementary…
A Shape-Based Functional Index for Objective Assessment of Pediatric Motor Function
Shashwat Kumar, Arafat Rahman, Robert Gutierrez +6
Clinical assessments for neuromuscular disorders, such as Spinal Muscular Atrophy (SMA) and Duchenne Muscular Dystrophy (DMD), continue to rely on subjective measures to monitor tr…
