RefineFly: Failure-Aware Post-Training for Aerial Vision-Language Navigation

RefineFly, a failure-aware RL post-training framework for end-to-end UAV-VLA policies, built on token-level proximal policy optimization (PPO), maintains dynamic failure memory within a two-stage scene curriculum to sustain learning from unresolved tasks as training shifts from empirical to balanced scene sampling.

RecoverFly: A Failure-Aware Reinforcement Learning Post-Training Framework for Aerial Vision-Language Navigation

RecoverFly is proposed, a failure-aware RL post-training framework for end-to-end UAV-VLA policies that adapts token-level RL for stable optimization of grammar-constrained autoregressive UAV actions, revisits unresolved failure cases to strengthen corrective learning and sample utilization, and combines a two-stage lo...
