A new research paper explores the capabilities of linear attention mechanisms within transformers, particularly in the context of in-context learning. The study establishes a nonlinearity-noise equivalence, demonstrating that linear attention can only capture the linear component of a nonlinear target function, with the remaining nonlinear structure acting as noise. This finding allows for the transfer of existing linear theory to nonlinear tasks and highlights a limitation of the linear attention model for studying nonlinear in-context learning. AI
