Extension of Correspondence Analysis to multiway data-sets through High Order SVD: a geometric framework
Olivier Coulaud, Alain Franc, Martina Iannacito
This paper presents an extension of Correspondence Analysis (CA) to tensors through High Order Singular Value Decomposition (HOSVD) from a geometric viewpoint. Correspondence analy…
