Compositional Generalization from Learned Skills via CoT Training: A Theoretical and Structural Analysis for Reasoning

ICLR 2026poster

Chain-of-Thought (CoT) training has markedly advanced the reasoning capabilities of large language models (LLMs), yet the mechanisms by which CoT training enhances generalization remain inadequately understood. In this work, we demonstrate that compositional generalization is fundamental: models sys…

Towards Understanding How Transformers Learn In-context Through a Representation Learning Lens

NeurIPS 2024poster

Pre-trained large language models based on Transformers have demonstrated remarkable in-context learning (ICL) abilities. With just a few demonstration examples, the models can implement new tasks without any parameter updates. However, it is still an open question to understand the mechanism of ICL…
