Beyond Reward: A Bounded Measure of Agent Environment Coupling
🤖AI Summary
Researchers introduce 'bipredictability' as a new metric to monitor reinforcement learning agents in real-world deployments, measuring interaction effectiveness through shared information ratios. The Information Digital Twin (IDT) system detects 89.3% of perturbations versus 44% for traditional reward-based monitoring, with 4.4x faster detection speed.
Key Takeaways
- →Bipredictability measures agent-environment coupling through information theory, providing early warning of system failures before performance drops.
- →The Information Digital Twin (IDT) auxiliary monitor significantly outperforms reward-based monitoring in detecting perturbations.
- →Normal RL agents operate at P = 0.33 ± 0.02, below the classical bound of 0.5, revealing inherent informational costs of decision-making.
- →The system enables proactive monitoring of deployed RL systems before traditional metrics show degradation.
- →Testing across 168 trials with SAC and PPO agents demonstrates robust performance across different perturbation types.
