In-context Learning and Induction Heads

The paper explores the concept of in-context learning in large language models, particularly transformers, and its relationship with induction heads, a specific type of attention mechanism. It discusses how the formation of induction heads correlates with improved in-context learning abilities and how they contribute to the overall functioning of the model.

The emergence of induction heads in transformer models is strongly correlated with a significant improvement in in-context learning abilities. Directly manipulating the formation of induction heads in models led to changes in their in-context learning performance, highlighting the crucial role of these mechanisms in adapting to new tasks without explicit retraining.
