Researchers analyze attention heads to understand in-context learning in LLMs

Researchers have developed a new framework called Task Subspace Logit Attribution (TSLA) to analyze how large language models perform in-context learning. This framework identifies specific attention heads responsible for recognizing tasks and learning from them, demonstrating their distinct roles. The study shows that these identified heads can align model states with task subspaces for recognition and rotate them for prediction, offering a unified explanation for various in-context learning mechanisms.
