detectors

Concept and data drift detectors.

This module exports both families.

• Concept drift (REQUIRES_FIT = False): feed a scalar, usually a prediction error, to add_element().

• Data drift (REQUIRES_FIT = True): compare input features to a reference with fit() or auto_fit_samples.

BaseDataDriftDetector and DataDriftResult are helpers, not detectors to pick.
