LLMs struggle with non-local dependencies in language learning

Researchers have explored the capacity of transformer-based Large Language Models (LLMs) to learn "k-antilocal languages," which are characterized by a lack of mutual information across any k contiguous symbols. Experiments involving these constructed languages demonstrated that LLMs achieved similar cross-entropy loss irrespective of the antilocality level. However, the models exhibited slower convergence rates when trained on more antilocal languages, suggesting that non-local dependencies pose a greater learning challenge, impacting speed rather than ultimate success. AI

IMPACT This research indicates that LLMs may require architectural or training improvements to efficiently handle complex, non-local linguistic structures.
