Multisubject Task-Related fMRI Data Processing via a Two-Stage Generalized Canonical Correlation Analysis
Paris A. Karakasis, Athanasios P. Liavas, Nicholas D. Sidiropoulos +2
Functional magnetic resonance imaging (fMRI) is one of the most popular methods for studying the human brain. Task-related fMRI data processing aims to determine which brain areas…
Learning Multivariate CDFs and Copulas using Tensor Factorization
Magda Amiridi, Nicholas D. Sidiropoulos
Learning the multivariate distribution of data is a core challenge in statistics and machine learning. Traditional methods aim for the probability density function (PDF) and are li…
Minimizing low-rank models of high-order tensors: Hardness, span, tight relaxation, and applications
Nicholas D. Sidiropoulos, Paris Karakasis, Aritra Konar
We consider the problem of finding the smallest or largest entry of a tensor of order N that is specified via its rank decomposition. Stated in a different way, we are given N sets…
