UP: Unbounded Positive Asymmetric Optimization for Breaking the Exploration-Stability Dilemma
arXiv:2607.06987v1 Announce Type: new Abstract: Reinforcement learning (RL) has become the standard paradigm for enhancing the complex reasoning capabilities of large language models (LLMs). To achieve sample efficiency, modern RL frameworks rely on importance sampling (IS). However, these algorithms suffer from an exploration-stability dilemma. Pure IS often leads to catastrophic training instability, while standard clipping mechanisms used to mitigate this instability strictly constrain the policy update budget. By formalizing the concept of Probability Capacity (Cap), we reveal that conserv
This research addresses a fundamental limitation in current reinforcement learning techniques, which are crucial for advancing large language models, indicating ongoing efforts to stabilize and improve AI training methodologies.
Improved reinforcement learning stability allows for more sample-efficient and robust training of advanced AI models, accelerating their development and deployment in real-world applications.
The proposed 'Unbounded Positive Asymmetric Optimization' offers a potential solution to the exploration-stability dilemma in RL, enabling more consistent and powerful AI model training than current clip-based methods.
