arXiv:2606.29182v1 Announce Type: cross 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. A notable recent example is AutoDiscovery, which uses "Bayesian surprise" - the belief shift an LLM undergoes after observing evidence for a hypothesis - as both a discovery metric and a reward for search. We first observe that AutoDiscovery treats surprisal as a static quantity, while surprisal in human reasoning is non-stationary - it i
The increasing sophistication of LLMs and the drive toward autonomous scientific discovery necessitates more advanced belief-updating mechanisms to manage long-horizon research.
This research addresses a core limitation in current AI-driven discovery, enabling more efficient and human-like iterative learning processes critical for complex scientific problems.
The methodology for how LLMs 'learn' and adapt their understanding based on new evidence shifts from static surprise to a non-stationary, context-dependent intelligence.
