Safe-RULE: Safe Reinforcement UnLEarning
Summary
Safe-RULE is a novel learning paradigm designed as a defense framework for offline safe reinforcement learning (Safe RL). Offline Safe RL, crucial for safety-critical systems such as robotics, learns policies from static datasets but is susceptible to data poisoning attacks that compromise safety and induce unsafe policy behavior. Safe-RULE addresses this by removing the influence of poisoned data without requiring retraining from scratch or access to the original training environment. This approach extends reinforcement unlearning to offline Safe RL by explicitly accounting for both task performance and safety constraints during the unlearning process. Experiments across benchmark Safe RL tasks demonstrate that Safe-RULE effectively enhances safety performance against data poisoning attacks.
Key takeaway
For Machine Learning Engineers developing safety-critical systems with offline Safe RL, data poisoning attacks pose a significant risk to policy safety. You should consider Safe-RULE as a defense mechanism to remove the influence of malicious data. This framework allows you to enhance safety performance against such attacks without the costly and time-consuming process of retraining from scratch or requiring access to the original training environment, thereby improving system robustness and reliability.
Key insights
Safe-RULE defends offline Safe RL from data poisoning by unlearning malicious data while preserving safety and task performance.
