)Arguments
- baseline
Baseline rule: first observed batch or an explicitly supplied reference batch.
- difficulty_limit
Absolute item-difficulty change triggering review.
- discrimination_limit
Absolute discrimination change triggering review.
- gaze_validity_drop
Maximum tolerated decrease in gaze validity.
- luminance_limit
Absolute luminance change triggering review.
- relative_metric_quantile
Quantile of absolute deltas used for process metrics without an externally meaningful absolute threshold.
- min_batches
Minimum number of batches per item for drift assessment.
