For questions related to tensor decomposition. A tensor decomposition is any scheme for expressing a tensor as a sequence of elementary operations acting on other, often simpler tensors.
In multilinear algebra, a tensor decomposition is any scheme for expressing a tensor as a sequence of elementary operations acting on other, often simpler tensors. Many tensor decompositions generalize some matrix decompositions.
The main tensor decompositions are:
- tensor rank decomposition;
- higher-order singular value decomposition;
- Tucker decomposition;
- matrix product states, and operators or tensor trains;
- hierarchical Tucker decomposition; and
- block term decomposition.
