tensorly.tucker_tensor.tucker_to_unfolded

tucker_to_unfolded(core, factors, mode=0, skip_factor=None, transpose_factors=False)[source]

Converts the Tucker decomposition into an unfolded tensor (i.e. a matrix)

Parameters

core : ndarray

core tensor

factors : ndarray list

list of matrices

mode : None or int list, optional, default is None

skip_factor : None or int, optional, default is None

if not None, index of a matrix to skip Note that in any case, modes, if provided, should have a lengh of tensor.ndim

transpose_factors : bool, optional, default is False

if True, the matrices or vectors in in the list are transposed

Returns

2D-array

unfolded tensor
