Regression Testing (AI)

The practice of retesting AI models after updates or modifications to ensure that previously working functionality has not been degraded and that known biases have not been reintroduced.

After updating an AI, checking that the update didn't break anything that was working before and didn't reintroduce old biases. Like a software update check: is everything still working as expected?

Regression testing is a governance safeguard that ensures AI updates do not introduce new risks or reintroduce previously addressed biases. Your framework should mandate regression testing as part of every model update cycle.
