Managing Regime Shifts and Concept Drift
Use population stability indexes, Kolmogorov–Smirnov tests, and rolling error deltas to flag drift. Automate retraining windows but gate releases with champion–challenger comparisons. Comment with your business cycle length, and we’ll suggest a cadence that balances stability with agility.
