Elicitation Matters: How Prompts and Query Protocols Shape LLM Surrogates under Sparse Observations
Ge Lei, Samuel J. Cooper
Large language models are increasingly used as surrogate models for low-data optimization, but their optimizer-facing prediction and its uncertainty remain poorly understood. We st…

Layerwise Recall and the Geometry of Interwoven Knowledge in LLMs
Ge Lei, Samuel J. Cooper
This study explores how large language models (LLMs) encode interwoven scientific knowledge, using chemical elements and LLaMA-series models as a case study. We identify a 3D spira…
