OR

class hybrid_learning.fuzzy_logic.tnorm_connectives.boolean.OR(*in_keys, bool_thresh=None, **kwargs)[source]

Bases: AbstractOR, BoolTorchOrNumpyOperation

Union/OR operation on binary masks and scalars. Store union of in_keys masks as out_key. OR with just one input key x is treated like x||True, i.e. identity.

Parameters: bool_thresh (float) –

static bool_numpy_operation(*inputs)[source]

OR on numpy-like vectors.

Parameters: inputs (ndarray) –
Return type: ndarray

static bool_torch_operation(*inputs)[source]

OR on torch tensors.

Parameters: inputs (Tensor) –
Return type: Tensor

cache_duplicates: bool: Whether to cache duplicate child operation outputs with duplicate out_key. If set to false, all children and children children are evaluated and the values of duplicate out_keys are evaluated several times and overwritten, possibly leading to more computational time while using less memory. Note that the order of children execution is determined by their order in in_keys, depth first for nested operations.

in_keys: Sequence[Union[str, 'Merge']]: The keys of segmentation masks to unite in given order. Keys are either constant strings or a merge operation.

keep_keys: Optional[Collection[str]]: The keys of intermediate outputs in all_out_keys which should be added to the return of a call. Default (None or empty collection): duplicate children outputs are cached but not returned to save memory.

out_key: str: The key to use to store the merge output in the annotations dict. Take care to not accidentally overwrite existing keys (cf. overwrite).

overwrite: Union[bool, Literal['noop']]: Whether to overwrite a value in the input dictionary when applying this operation. The operation is defined in operation(). The key that may be overwritten is stored in out_key. An exception is raised if this is False and the key exists. If set to 'noop' and out_key is in the given annotations dict, it is returned unchanged.

replace_none: Optional[Any]: If not None, any received None value is replaced by the given value. This is done only for computation, the None value in the received dict is left unchanged. Key-value pairs with None value may come from the input or from child operations.

skip_none: bool: If set to True, when a None input value is encountered simply None is returned. If False, an error is raised.
