Researcher Speculates: LLMs Explore Hypothesis Space in Near-Solomonoff Order

jd_pressman · x · 2026-10-10

A discussion thread on how deep nets versus human mathematicians search hypothesis space. The author argues that even if deep nets start with complex hypotheses and whittle them down, human mathematicians — and LLMs doing math and physics — clearly explore hypotheses in something closer to Solomonoff order (simplest programs first). He further guesses the mechanism: models start from a library of programs closely based on input data, then generalize by fitting programs that reproduce/predict the target data across more inputs while keeping program size fixed.
