A Novel PARAFAC Model for Processing the Nested Vector-Sensor Array

open access: yesSensors, 2018
In this paper, a novel parallel factor (PARAFAC) model for processing the nested vector-sensor array is proposed. It is first shown that a nested vector-sensor array can be divided into multiple nested scalar-sensor subarrays.

Three-Mode Factor Analysis by Means of Candecomp/Parafac

open access: yesPsychometrika, 2014
A three-mode covariance matrix contains covariances of N observations (e.g., subject scores) on J variables for K different occasions or conditions. We model such an JK×JK covariance matrix as the sum of a (common) covariance matrix having Candecomp/Parafac form, and a diagonal matrix of unique variances.
