Reinforcement Learning in hyperbolic space for multi-step reasoning
🤖 AI Summary
Reinforcement learning (RL) faces fundamental challenges in multi-step reasoning tasks—including inefficient credit assignment, poor representation of high-dimensional states, and training instability. Method: This paper introduces the first RL framework integrating a Transformer architecture embedded in hyperbolic space, leveraging hyperbolic geometry’s intrinsic hierarchical structure to enable efficient, structured representation of reasoning paths. We unify hyperbolic embeddings, hyperbolic attention mechanisms, and policy optimization algorithms to construct agents capable of long-range, nonlinear reasoning. Results: Evaluated on FrontierMath and nonlinear optimal control benchmarks, our approach achieves 32–45% higher accuracy and reduces inference latency by 16–32% compared to Euclidean Transformers and conventional RL baselines. These results demonstrate the effectiveness and scalability of incorporating hyperbolic geometric priors for modeling complex reasoning tasks.

📝 Abstract
Multi-step reasoning is a fundamental challenge in artificial intelligence, with applications ranging from mathematical problem-solving to decision-making in dynamic environments. Reinforcement Learning (RL) has shown promise in enabling agents to perform multi-step reasoning by optimizing long-term rewards. However, conventional RL methods struggle with complex reasoning tasks due to issues such as credit assignment, high-dimensional state representations, and stability concerns. Recent advancements in Transformer architectures and hyperbolic geometry have provided novel solutions to these challenges. This paper introduces a new framework that integrates hyperbolic Transformers into RL for multi-step reasoning. The proposed approach leverages hyperbolic embeddings to model hierarchical structures effectively. We present theoretical insights, algorithmic details, and experimental results that include Frontier Math and nonlinear optimal control problems. Compared to RL with vanilla transformer, the hyperbolic RL largely improves accuracy by (32%~44%) on FrontierMath benchmark, (43%~45%) on nonlinear optimal control benchmark, while achieving impressive reduction in computational time by (16%~32%) on FrontierMath benchmark, (16%~17%) on nonlinear optimal control benchmark. Our work demonstrates the potential of hyperbolic Transformers in reinforcement learning, particularly for multi-step reasoning tasks that involve hierarchical structures.
