- class tltorch.CPTensorized(*args, **kwargs)[source]
Methods
from_tensor
(tensor, tensorized_shape[, rank])Create a factorized tensor by decomposing a full tensor
new
(tensorized_shape, rank[, device, dtype])Main way to create a Tensorized Matrix
- classmethod new(tensorized_shape, rank, device=None, dtype=None, **kwargs)[source]
Main way to create a Tensorized Matrix
- Parameters
- tensorized_shapetuple[int]
- rankint, ‘same’ or float
rank of the decomposition
- n_matricestuple or int, default is ()
if not (), indicates how many matrices have to be jointly factorized
- factorization{‘CP’, ‘TT’, ‘Tucker’}, optional
Tensor factorization to use to decompose the tensor, by default ‘CP’
- Returns
- TensorizedTensor
Tensor in Tensorized and Factorized form.
- Raises
- ValueError
If the factorization given does not exist.
