UniIntervene++ is an adaptive intervention agent that learns to balance autonomous execution and assisted behaviors during online reinforcement learning. It models the evolving policy, trajectory correction, and task-structured CodePolicy as Options in a unified semi‑Markov decision process, learning their values online. The agent periodically probes the policy to keep control allocation responsive, and uses coupled experience learning to improve both the policy and future interventions, achieving an 89.67% success rate on five real‑world tasks while cutting human intervention by 94.6%.

SEVI (Safe Evidential Real-World Reinforcement Learning) is a framework that adds a safety intervention layer to real‑world policy learning. It uses an Evidential Safety Critic to estimate both future constraint‑violation risk and epistemic uncertainty in a single forward pass, and overrides unsafe or poorly supported actions with an offline‑trained recovery policy. Experiments on simulated manipulation tasks and a real‑world USB insertion task show that SEVI improves trajectory‑level safety prediction, task success, and reduces unsafe events by 13.4–57.1% compared to other safe RL baselines.

Background: Offline reinforcement learning (RL) enables effective policies to be trained from large, previously collected datasets and subsequently improved through limited online interaction. This offline-to-online RL (O2O-RL) paradigm is particularly promising in nonstationary domains where interaction is costly or potentially hazardous.
