Mechanistic Interpretability Reveals Cross-Lingual Syntactic Transfer in Multilingual LMs

Researchers have utilized mechanistic interpretability techniques to investigate syntactic mechanisms within multilingual language models. Their study focused on four models and three specific constructions: subject-verb number agreement, anaphoric pronoun gender agreement, and filler-gap object extraction. The findings indicate consistent cross-lingual transfer of these mechanisms, with the degree of transfer correlating with the typological similarity between languages. This research offers new hypotheses regarding cross-linguistic syntactic structures and multilingual processing, suggesting that language models can contribute to linguistic theory. AI
