torch_concepts.nn.BlackBoxTaskOnly

class BlackBoxTaskOnly(*args, lightning: bool = False, **kwargs)

BlackBox model.

This model implements a standard neural network architecture for predicting tasks only, without explicit concept bottleneck or interpretable intermediate representations. It uses a backbone mapping the raw input to the latent representation, then a linear head.

Parameters:

• input_size (int) – Dimensionality of input features.

• annotations (Annotations) – Annotation object for output variables.

• task_names (Union[List[str], str]) – Task names to predict.

• lightning (bool, optional) – Enable Lightning training. Default False.

• **kwargs – Additional arguments for BaseModel.

task_annotations

Sub-annotation restricted to task concepts only. Use this to build ConceptLoss / ConceptMetrics.

Type:

Annotations

task_concept_idx

Concept-level column indices used to slice the ground-truth target tensor to match the task-only output.

Type:

List[int]

Example

>>> from torch_concepts.annotations import Annotations
>>> ann = Annotations(labels=['c1', 'task'], cardinalities=[1, 1])
>>> model = BlackBoxTaskOnly(input_size=8, annotations=ann, task_names=['task'])
>>> out = model(torch.randn(2, 8))

__init__(input_size: int, annotations: Annotations, task_names: List[str] | str, lightning: bool = False, **kwargs) → None
