SteinGate: Tail-Sensitive Safe Reinforcement Learning via Stein Discrepancy

Yassine Chemingui, Chenhua Fan, Honghao Wei, Janardhan Rao Doppa

Safe reinforcement learning typically enforces safety by bounding expected cumulative costs, a criterion that often fails to detect rare but catastrophic tail events. To overcome these limitations, this paper introduces SteinGate, a boundary-aware distributional safety certificat…Read more
