tensorly.random.random_tt

random_tt(shape, rank, full=False, random_state=None, **context)[source]

Generates a random TT/ttrain tensor

Parameters:
shapetuple

shape of the tensor to generate

rankint

rank of the TT decomposition must verify rank[0] == rank[-1] ==1 (boundary conditions) and len(rank) == len(shape)+1

fullbool, optional, default is False

if True, a full tensor is returned otherwise, the decomposed tensor is returned

random_statenp.random.RandomState
contextdict

context in which to create the tensor

Returns:
TT_tensorND-array or 3D-array list
  • ND-array : full tensor if full is True
  • 3D-array list : list of factors otherwise
