dataeval.shift.DriftDomainClassifierStats¶

class dataeval.shift.DriftDomainClassifierStats¶

Statistics from Multivariate Domain Classifier drift detection.

p_val¶

AUROC score used as proxy for drift significance.

Type:¶

float

fold_aurocs¶

Per-fold AUROC values from stratified K-fold cross-validation. Shape is (n_folds,). Variance across folds indicates stability of the AUROC estimate.

Type:¶

NDArray[np.float32]

feature_importances¶

Mean feature importances (split-based) from LightGBM, averaged across CV folds. Shape is (n_features,). Higher values indicate features that contribute more to distinguishing reference from test data.

Type:¶

NDArray[np.float32]
