Positional Cognitive Specialization: Where Do LLMs Learn to Comprehend and Speak Your Language?

AAAI 2026technical

Adapting large language models (LLMs) to new languages is an expensive and opaque process. Understanding how language models acquire new languages and multilingual abilities is key to achieve efficient adaptation. Prior work on multilingual interpretability research focuses primarily on how trained

Label-Aware Hyperbolic Embeddings for Fine-grained Emotion Classification

ACL 2023long

Fine-grained emotion classification (FEC) is a challenging task. Specifically, FEC needs to handle subtle nuance between labels, which can be complex and confusing. Most existing models only address text classification problem in the euclidean space, which we believe may not be the optimal solution…
