Can Post-Training Transform LLMs into Causal Reasoners?

Junqi Chen, Sirui Chen, Chaochao Lu

Causal inference is essential for decision-making but remains challenging for non-experts. While large language models (LLMs) show promise in this domain, their precise causal esti…

Beyond Surface Structure: A Causal Assessment of LLMs' Comprehension Ability

Yujin Han, Lei Xu, Sirui Chen +2

Large language models (LLMs) have shown remarkable capability in natural language tasks, yet debate persists on whether they truly comprehend deep structure (i.e., core semantics)…
