model_evaluation(alternative_metrics: Optional[Dict[str, Metric]] = None, area_range: Tuple[float, float] = (1024, 9216), image_properties: Optional[List[Dict[str, Any]]] = None, prediction_properties: Optional[List[Dict[str, Any]]] = None, random_state: int = 42, **kwargs) → Suite[source]#

Suite for evaluating the model’s performance over different metrics, segments, error analysis, comparing to baseline, and more.

List of Checks:

List of Checks#
Check Example	API Reference
Class Performance	`ClassPerformance`
Mean Average Precision Report	`MeanAveragePrecisionReport`
Mean Average Recall Report	`MeanAverageRecallReport`
Train Test Prediction Drift	`TrainTestPredictionDrift`
Simple Model Comparison	`SimpleModelComparison`
Confusion Matrix	`ConfusionMatrixReport`
Image Segment Performance	`ImageSegmentPerformance`
Model Error Analysis check	`ModelErrorAnalysis`

Parameters

alternative_metricsDict[str, Metric], default: None

A dictionary of metrics, where the key is the metric name and the value is an ignite.Metric object whose score should be used. If None are given, use the default metrics.

area_range: tuple, default: (32**2, 96**2)

Slices for small/medium/large buckets. (For object detection tasks only)

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.

prediction_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. - ‘class_id’ - for properties that return the class_id. This is used because these

properties are later matched with the VisionData.label_map, if one was given.

random_stateint, default: 42

random seed for all checks.

**kwargsdict

additional arguments to pass to the checks.

Returns

Suite: A suite for evaluating the model’s performance.
