Uncovering Symmetry Transfer in Large Language Models via Layer-Peeled Optimization

arXiv CS.AI

ArXi:2605.12756v1 Announce Type: cross Large language models (LLMs) are pretrained by minimizing the cross-entropy loss for next-token prediction. In this paper, we study whether this optimization strategy can induce geometric structure in the learned model weights and context embeddings. We approach this problem by analyzing a constrained layer-peeled optimization program, which serves as a mathematically tractable surrogate for LLMs by treating the output projection matrix and last-layer context embeddings as optimization variables.
