CCCaption: Dual-Reward Reinforcement Learning for Complete and Correct Image Captioning

CVPR 2026

Image captioning remains a fundamental task for vision-language understanding, yet ground-truth supervision still relies predominantly on human-annotated references.Because human annotations reflect subjective preferences and expertise, ground-truth captions are often incomplete or even incorrect, w

Towards On-Policy SFT: Distribution Discriminant Theory and its Applications in LLM Training

ICML 2026poster

Supervised fine-tuning (SFT) is computationally efficient but often yields inferior generalization compared to reinforcement learning (RL). This gap is primarily driven by RL’s use of on-policy data. We propose a framework to bridge this chasm by enabling On-Policy SFT. We first present ***Distribut…
