About this paper

Raghav Ramji, Keshav Ramji

A two-stage analogical prompting method enables large language models to perform sophisticated inductive linguistic reasoning on low-resource languages. The approach significantly improves performance on linguistic puzzles, with Llama-3.1-405B-Instruct achieving over 70% Exact Match on the modeLing dataset.

Key insights

  • Frontier large language models exhibit a strong parametric understanding of language families, often inferring them more effectively than using provided oracle labels.
  • The process of linguistic reasoning in LLMs can be effectively decomposed into a stage of analogical exemplar generation (e.g., by a specialized multilingual model) and a subsequent stage of rule deduction and application (by a generalist model).
  • Linguistics Olympiad-style puzzles serve as robust benchmarks for inductive reasoning, revealing nuanced capabilities and limitations in LLMs, including their handling of language isolates and uncertainty-based refusal.
