data_integrity#

data_integrity(image_properties: Optional[List[Dict[str, Any]]] = None, n_show_top: int = 5, label_properties: Optional[List[Dict[str, Any]]] = None, **kwargs) → Suite[source]#

Create a suite that includes integrity checks.

List of Checks:

List of Checks#
Check Example	API Reference
Image Property Outliers	`ImagePropertyOutliers`
Label Property Outliers	`LabelPropertyOutliers`

Parameters

image_propertiesList[Dict[str, Any]], default: None

List of properties. Replaces the default deepchecks properties. Each property is a dictionary with keys ‘name’ (str), ‘method’ (Callable) and ‘output_type’ (str), representing attributes of said method. ‘output_type’ must be one of: - ‘numeric’ - for continuous ordinal outputs. - ‘categorical’ - for discrete, non-ordinal outputs. These can still be numbers,

but these numbers do not have inherent value.

For more on image / label properties, see the vision_properties_guide

n_show_topint , default: 5

number of samples to show from each direction (upper limit and bottom limit)

label_propertiesList[Dict[str, Any]], default: None

but these numbers do not have inherent value.

For more on image / label properties, see the vision_properties_guide

**kwargsdict

additional arguments to pass to the checks.

Returns

Suite: A suite that includes integrity checks.

>>> suite = data_integrity()
>>> result = suite.run()
>>> result.show()

Run all checks.

Parameters

train_dataset: Optional[VisionData] , default None: object, representing data an estimator was fitted on
test_datasetOptional[VisionData] , default None: object, representing data an estimator predicts on
modelnn.Module , default None: A scikit-learn-compatible fitted estimator instance
model_name: str , default: ‘’: The name of the model
scorersOptional[Mapping[str, Metric]] , default: None: dict of scorers names to a Metric
scorers_per_classOptional[Mapping[str, Metric]] , default: None: dict of scorers for classification without averaging of the classes. See <a href= “https://scikit-learn.org/stable/modules/model_evaluation.html#from-binary-to-multiclass-and-multilabel”> scikit-learn docs</a>
deviceUnion[str, torch.device], default: ‘cpu’: processing unit for use
random_stateint: A seed to set for pseudo-random functions
n_samplesOptional[int], default: None: number of samples
with_displaybool , default: True: flag that determines if checks will calculate display (redundant in some checks).
train_predictions: Optional[Dict[int, Union[Sequence[torch.Tensor], torch.Tensor]]] , default None: Dictionary of the model prediction over the train dataset (keys are the indexes).
test_predictions: Optional[Dict[int, Union[Sequence[torch.Tensor], torch.Tensor]]] , default None: Dictionary of the model prediction over the test dataset (keys are the indexes).

Returns

SuiteResult: All results by all initialized checks
