arXiv:2606.05859v1 Announce Type: new Abstract: Latent reasoning has emerged as a promising alternative to discrete Chain-of-Thought (CoT) in large language models (LLMs), enabling more expressive reasoning by operating over continuous representations. However, the inherently deterministic nature of continuous representations limits policy exploration in reinforcement learning (RL). To address this, we propose TARPO (Token-Wise Latent-Explicit Reasoning via Action-Routing Policy Optimization), a pure RL framework that adaptively switches between discrete token generation and continuous latent
The continuous evolution of large language models is driving research into more sophisticated and adaptive reasoning mechanisms to overcome limitations of existing methods.
Improving AI reasoning capabilities is crucial for developing more autonomous and robust AI systems applicable across a wider range of complex tasks.
This research introduces a novel reinforcement learning framework that allows LLMs to dynamically choose between discrete and continuous reasoning, potentially enhancing policy exploration and performance.
