t3toolbox.OLD_uniform.get_original_structure

t3toolbox.OLD_uniform.get_original_structure(masks: UniformEdgeWeights)

Get original (unpadded) structure of a uniform Tucker tensor train.

Parameters:

masks (UniformTuckerTensorTrainEdgeMasks) – Edge masks for the uniform Tucker tensor train

Returns:

Structure of the unpadded Tucker tensor train

Return type:

t3.T3Structure

Examples

>>> import numpy as np
>>> import t3toolbox.tucker_tensor_train as t3
>>> import t3toolbox.uniform_tucker_tensor_train as ut3
>>> x = t3.t3_corewise_randn(((14,15,16), (4,6,5), (1,3,2,1)))
>>> cores, masks = ut3.t3_to_ut3(x)
>>> print(ut3.get_uniform_structure(cores))
(3, 16, 6, 3)
>>> print(ut3.get_original_structure(masks))
((14, 15, 16), (4, 6, 5), (1, 3, 2, 1))
