Title: Modelling hidden structure of signals in group data analysis with modified (Lr, 1) and block-term decompositions,
Abstract: This work is devoted to elaboration on the idea to use block term
decomposition for group data analysis and to raise the possibility of modelling
group activity with (Lr, 1) and Tucker blocks. A new generalization of block
tensor decomposition was considered in application to group data analysis.
Suggested approach was evaluated on multilabel classification task for a set of
images. This contribution also reports results of investigation on clustering
with proposed tensor models in comparison with known matrix models, namely
common orthogonal basis extraction and group independent component analysis.
