Timothy Pistotti, Jason Brown, Michael Witbrock
Recent studies employing Large Language Models (LLMs) to test the Argument from the Poverty of the Stimulus (APS) have yielded contrasting results across syntactic phenomena. This…
Exploring Gaps in the APS: Direct Minimal Pair Analysis in LLM Syntactic Assessments
Timothy Pistotti, Jason Brown, Michael Witbrock
Recent studies probing the Argument from the Poverty of the Stimulus (APS) have applied Large Language Models (LLMs) to test the learnability of complex syntax through surprisal-ba…
Psychology-Driven Enhancement of Humour Translation
Yuchen Su, Yonghua Zhu, Yang Chen +2
Humour translation plays a vital role as a bridge between different cultures, fostering understanding and communication. Although most existing Large Language Models (LLMs) are cap…
