Webtensor decompositions can be considered to be higher-order extensions of the matrix sin-gular value decomposition:CANDECOMP/PARAFAC (CP) decomposes a tensor as a sum of rank-one tensors, and the Tucker decomposition is a higher-order form of principal component analysis. There are many other tensor decompositions, including INDSCAL, Web(CP) decomposition can also be considered as a sparse method. More speciﬁcally, a CP decomposition can be considered as a speciﬁc type of Tucker factorization that generates a very sparse core tensor, i.e. a core tensor with non-zero values only at the super-diagonal positions. However, CP does not generate sparse factor matrices and
