Toward Generalist Autonomous Research via Hypothesis-Tree Refinement
English summary
The paper introduces Arbor, an AI framework for autonomous scientific research that coordinates strategic exploration, isolated hypothesis testing, and knowledge accumulation. Arbor features a long-lived coordinator, short-lived executors, and a Hypothesis Tree Refinement (HTR) system that links hypotheses, artifacts, evidence, and insights over time. The framework outperforms other AI agents across diverse research tasks by enabling iterative, cumulative improvement without constant human intervention.
Chinese summary
该论文提出Arbor，一个面向自主科学研究的AI框架，通过战略协调、隔离式假设检验和知识累积，将探索、实验与抽象整合为迭代过程。框架包含长期协调器、短期执行器以及假设树精炼（HTR）系统，持续连接假设、工件、证据和洞察。在多项研究任务中，Arbor的表现优于其他AI代理，无需持续人工干预即可实现自主研究的累积性提升。
