property barycenter: TorchCategoricalDistribution

Return the barycenter of the credal set.

clone(*, memory_format: memory_format = torch.preserve_format) → Self

Return a copy of the array.

contains(probabilities: Tensor) → Tensor

Check whether probabilities are inside the intervals.

cpu(memory_format: memory_format = torch.preserve_format) → Self

Move the array to the CPU.

cuda(device: device | str | None = None, non_blocking: bool = False, memory_format: memory_format = torch.preserve_format) → Self

Move the array to the GPU.

detach() → Self

Return a detached version of the array.

property device: device

Device of the array.

property dtype: dtype

Data type of the array.

classmethod from_sample(sample: Sample[TorchCategoricalDistribution]) → Self

Create a credal set from a finite sample.

Parameters:

sample – The sample to create the credal set from.

Returns:

The created credal set.

classmethod from_torch_sample(sample: TorchSample[TorchCategoricalDistribution]) → Self

Create a credal set from categorical distribution samples.

lower_bounds: torch.Tensor

property mH: Self

The adjoint (conjugate) transposed version of the underlying array.

property mT: Self

The transposed version of the underlying array.

property ndim: int

Number of dimensions.

property num_classes: int

Get the number of classes.

numpy(*, force: bool = False) → NDArray[Any]

Convert to a numpy array.

permitted_functions = {}

permute(*dims: Size | int | tuple[int] | list[int]) → Self

Return a permuted version of the array.

classmethod primary_protected_name() → str

Return the first protected field (dict order).

protected_axes: ClassVar[dict[str, int]] = {'lower_bounds': 1, 'upper_bounds': 1}

property protected_shape: tuple[int, ...]

Protected trailing shape of the primary field.

protected_value() → TorchProtectedValue

Return the primary protected value.

protected_values(func: Callable | None = None) → dict[str, TorchProtectedValue] | None

Return the size of the array along the given dimension.

to(*args: Any, **kwargs: Any) → Self

Move and/or cast the tensor, mirroring torch.Tensor.to.

to_device(device: Literal['cpu'], /, *, stream: int | Any | None = None) → Self

transpose(dim0: int, dim1: int) → Self

Return a transposed version of the array.

type = 'categorical'

upper_bounds: torch.Tensor

width() → Tensor

Compute interval width for each class.

with_protected_value(value: TorchProtectedValue) → Self
