FBOS-RL: Feedback-Driven Bi-Objective Synergistic Reinforcement Learning
The article introduces FBOS-RL, a new framework for reinforcement learning that enhances training efficiency. It combines Feedback-Guided Exploration Enhancement with two training objectives: Exploitation-oriented Policy Alignment and Exploration-oriented Capability Cultivation. Experimental results show that FBOS-RL significantly outperforms existing methods in both speed and final performance.
- ▪FBOS-RL addresses limitations in traditional reinforcement learning methods like GRPO.
- ▪The framework utilizes feedback from the environment to improve exploration and policy alignment.
- ▪Extensive experiments indicate that FBOS-RL achieves faster learning and higher performance ceilings.
