Toward Generalist Autonomous Research via Hypothesis-Tree Refinement

A new framework named Arbor has been introduced to facilitate autonomous research through a process called Hypothesis Tree Refinement (HTR), which connects hypotheses, evidence, and insights over time. This system allows an AI agent to autonomously manage research strategies and execute experiments, enhancing the efficiency of scientific exploration.
