arXiv:2606. 29182v1 Announce Type: new Abstract: Open-ended scientific discovery with large language models (LLMs) increasingly operates as a long-horizon loop of hypothesis search and verification, where a reward signal guides which hypotheses to test next.
arXiv:2606. 11851v1 Announce Type: new Abstract: Open-ended scientific discovery asks agents to move beyond executing analyses for predefined questions.
arXiv:2606. 08532v5 Announce Type: replace Abstract: Modern artificial intelligence excels at prediction but cannot explain.
arXiv:2607. 01131v1 Announce Type: cross Abstract: Autonomous scientific discovery systems offer the potential to accelerate research by automating the process of hypothesis generation and validation.
arXiv:2602. 06448v2 Announce Type: replace-cross Abstract: Large Language Model (LLM)-based scientific agents have accelerated scientific discovery, yet they often suffer from significant inefficiencies due to adherence to fixed initial priors.
Principia is an LLM-based framework that constructs and refines scientific principles during test-time discovery. It generates comparative causal hypotheses from related inputs and outcomes, synthesizes recurring relationships into inductive principles, and iteratively updates these principles as new observations are obtained. Across benchmarks in molecular optimization, protein engineering, gene perturbation, and molecular property prediction, Principia outperforms baselines that rely on internal knowledge, external sources, or experience summaries, producing plausible principles consistent with scientific literature.
