for customized applications and user needs. Recently, RL [ 71,77] has emerged as a powerful post-training technique, enabling models to learn from feedback and align with human values. RL in MLLMs can be broadly categorized into two paradigms: (1) RL from human/AI 2 feedback (RLHF) [ 31,50,57,63,70,74–76,85,88,89,92,99... | https://arxiv.org/abs/2505.17534v1 |
