About this paper
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.
