Decompositions of higher-order tensors

Michele Gallo
University of Naples – L’Orientale.


Tensors are a highly flexible algebraic architecture for storing data and describing multilinear relationships between entities in a compact form. A generic nth-order tensor stores data along n indices and can be described as a generalization of simple structures such as matrices and three-way array, which are special cases of 2nd-order (2 indices) tensors and 3th-order (3 indices) tensors. CANDECOMP/PARAFAC (CP) is considered to be higher-order extensions of the matrix singular value decomposition, as well as other tensor decomposition and variants for compositional data.
