t3toolbox.uniform_tucker_tensor_train.t3_to_ut3

t3toolbox.uniform_tucker_tensor_train.t3_to_ut3(x: t3toolbox.tucker_tensor_train.TuckerTensorTrain, use_jax: bool = False) → UniformTuckerTensorTrain

Convert TuckerTensorTrain to UniformTuckerTensorTrain.

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), (3, 3, 2, 4), stack_shape=(2,3))
>>> uniform_x = ut3.t3_to_ut3(x)  # Convert t3 -> ut3
>>> x2 = ut3.ut3_to_t3(uniform_x, stack_t3s=True)  # Convert ut3 -> t3
>>> dense_x = x.to_dense()
>>> dense_x2 = x2.to_dense()
>>> print(np.linalg.norm(dense_x - dense_x2))
