}

Temporal drift configuration for simulating distribution changes over time.

This enables generation of data that shows realistic temporal evolution, useful for training drift detection models and testing temporal robustness.

Fields

enabled: bool

Enable temporal drift simulation.

amount_mean_drift: f64

Amount mean drift per period (e.g., 0.02 = 2% mean shift per month). Simulates gradual inflation or business growth.

amount_variance_drift: f64

Amount variance drift per period (e.g., 0.01 = 1% variance increase per month). Simulates increasing volatility over time.

anomaly_rate_drift: f64

Anomaly rate drift per period (e.g., 0.001 = 0.1% increase per month). Simulates increasing fraud attempts or degrading controls.

concept_drift_rate: f64

Concept drift rate - how quickly feature distributions change (0.0-1.0). Higher values cause more rapid distribution shifts.

sudden_drift_probability: f64

Sudden drift events - probability of a sudden distribution shift in any period.

sudden_drift_magnitude: f64

Magnitude of sudden drift events when they occur (multiplier).

seasonal_drift: bool

Seasonal drift - enable cyclic patterns that repeat annually.

drift_start_period: u32

Drift start period (0 = from beginning). Use to simulate stable baseline before drift.

drift_type: DriftType

Drift type: “gradual”, “sudden”, “recurring”, “mixed”
