A new research paper explores how linguistic structure influences the effectiveness of in-context learning (ICL) in large language models. The study found that certain linguistic operations, like forward inflection, can be effectively amortized into latent task representations, allowing for zero-shot inference that surpasses traditional ICL. However, other operations, such as arbitrary pairings like antonymy, do not benefit from this amortization and perform poorly. The research highlights that productive rules can be encoded into latent representations more efficiently than memorized pairings, suggesting a deeper understanding of linguistic properties is key for optimizing LLM performance.
