New research quantifies attention heads needed for multi-task computation

A new research paper explores the capabilities of multi-head attention layers in producing vector representations for diverse computational tasks. The study establishes theoretical bounds on the number of attention heads needed for specific scenarios, such as computing the minimum and maximum values in a list using linear predictors. It also analyzes the requirements for polynomial threshold functions to compute the XOR of a bit string, demonstrating that the product of heads and polynomial degree must be at least n. AI
