New metric reveals how language models process metaphor

Researchers have developed a new metric called conditional scale entropy (CSE) to analyze how decoder-only language models process metaphors. CSE measures the breadth of computational engagement across different frequency scales within a transformer's layers. Studies using CSE revealed that metaphorical tokens consistently activate a wider range of computational scales compared to literal tokens in models ranging from 124 million to 20 billion parameters, including architectures like GPT-2, LLaMA-2, and GPT-oss.
