async classmethod async_run(sample_list: List[Sample], model: ModelAPI, **kwargs)#

Creates a task to run the robustness measure.

Parameters:

• sample_list (List[Sample]) – The input data to be transformed.

• model (ModelAPI) – The model to be used for evaluation.

• **kwargs – Additional arguments to be passed to the robustness measure.

Returns:

The task that runs the robustness measure.

Return type:

asyncio.Task

abstract async static run(sample_list: List[Sample], model: ModelAPI, **kwargs) → List[Sample]#

Abstract method that implements the robustness measure.

Parameters:

• sample_list (List[Sample]) – The input data to be transformed.

• model (ModelAPI) – The model to be used for evaluation.

• **kwargs – Additional arguments to be passed to the robustness measure.

Returns:

The transformed data based on the implemented robustness measure.

Return type:

List[Sample]

static transform(sample_list: List[Sample], prob: float | None = 1.0, count: int = 1) → List[Sample]#

Add typos to the text samples in the given sample list.

Parameters:

• sample_list (List[Sample]) – A list of samples to be transformed.

• prob (Optional[float]) – The probability of adding a typo to each sample. Defaults to 1.0, which means all words will be transformed.

• count – Number of variations to create.

Returns:

The transformed sample list with added typos.

Return type:

List[Sample]
