Interview: 'how do you make an RL policy safe to deploy?'
hardAnswer
- (1) Simulation validation across held-out scenarios + adversarial tests.
- (2) Formal / conservative bounds where possible (CMDP).
- (3) Safety layer: monitor / veto extreme actions at runtime.
- (4) Human-in-the-loop for edge cases.
- (5) Shadow deployment first (log-only), then gradual rollout with A/B guardrails.
- (6) Continuous monitoring: distribution shift, reward drift, action distribution, incident rate.
- (7) Rollback plan.
- Safety-critical RL is engineering-heavy.
Check yourself — multiple choice
- Just deploy
- Sim validation + adversarial + conservative bounds + safety layer + HITL + shadow + gradual rollout + continuous monitoring (drift, incidents) + rollback plan — safety = engineering
- Random
- Not real
Safe RL deploy: sim + adversarial + safety layer + HITL + shadow + rollback.
