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…
An Accelerated Stochastic Gradient for Canonical Polyadic Decomposition
Ioanna Siaminou, Athanasios P. Liavas
We consider the problem of structured canonical polyadic decomposition. If the size of the problem is very big, then stochastic gradient approaches are viable alternatives to class…
Accelerated Stochastic Gradient for Nonnegative Tensor Completion and Parallel Implementation
Ioanna Siaminou, Ioannis Marios Papagiannakos, Christos Kolomvakis +1
We consider the problem of nonnegative tensor completion. We adopt the alternating optimization framework and solve each nonnegative matrix completion problem via a stochastic vari…
