Elliptically-Contoured Tensor-variate Distributions with Application to Improved Image Learning

no code implementations13 Nov 2022 Carlos Llosa-Vite, Ranjan Maitra

Statistical analysis of tensor-valued data has largely used the tensor-variate normal (TVN) distribution that may be inadequate when data comes from distributions with heavier or lighter tails.

Quantitative Matching of Forensic Evidence Fragments Utilizing 3D Microscopy Analysis of Fracture Surface Replicas

no code implementations24 Sep 2021 Bishoy Dawood, Carlos Llosa-Vite, Geoffrey Z. Thompson, Barbara K. Lograsso, Lauren K. Claytor, John Vanderkolk, William Meeker, Ranjan Maitra, Ashraf Bastawros

In this study, a statistical analysis comparison protocol was applied to a set of 3D topological images of fractured surface pairs and their replicas to provide confidence in the quantitative statistical comparison between fractured items and their replicas.

Reduced-Rank Tensor-on-Tensor Regression and Tensor-variate Analysis of Variance

no code implementations18 Dec 2020 Carlos Llosa-Vite, Ranjan Maitra

Fitting regression models with many multivariate responses and covariates can be challenging, but such responses and covariates sometimes have tensor-variate structure.
