How drift alerts are generated
Z-Score Anomaly
Flags a metric when it deviates more than 2.0โ3.0ฯ from the rolling mean. Severity scales with the deviation magnitude.
PSI (Population Stability Index)
Measures distribution shift of similarity scores vs baseline. PSI > 0.10 = INFO, > 0.25 = WARNING. Borrowed from financial risk modeling.
EWMA Control Charts
Exponentially weighted moving average with computed upper/lower control limits. Any point outside the limits triggers a WARNING.
PELT Change-Point
Detects structural breaks in the time series โ pinpoints the exact run where the model's behaviour changed.
