Non-Parametric Structural Priors for Geometry Theorem Prediction

arXiv:2603.04852v2 Announce Type: replace Abstract: Multi-step theorem prediction is a central challenge in geometry problem solving. Existing neural-symbolic approaches rely heavily on supervised parametric models, which exhibit limited generalization to evolving theorem libraries. In this work, we explore training-free theorem prediction through the lens of in-context learning (ICL). We identify a critical scalability bottleneck, termed Structural Drift: as reasoning depth increases, the performance of vanilla ICL degrades sharply, often collapsing to near zero. We attribute this failure to

Why this matters
Why now

The paper identifies a critical scalability bottleneck, 'Structural Drift,' in existing neural-symbolic approaches for multi-step theorem prediction, indicating a current challenge in AI problem-solving.

Why it’s important

This work points to limitations in current AI methods for complex geometric reasoning, highlighting the need for more robust generalization capabilities beyond supervised parametric models.

What changes

The focus might shift towards more non-parametric, training-free AI approaches or hybrid methods that can overcome 'Structural Drift' and enhance generalization in problem-solving.
