Transformer learning theory explained via softmax approximation

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new theoretical framework to understand how Transformer networks learn regression tasks. Their approach uses a "softmax partition of unity" to combine local function approximations, leveraging the attention mechanism for spatial localization. The study demonstrates that a Transformer with just two encoder blocks can achieve a uniform approximation error for certain continuous functions, leading to near minimax-optimal generalization error bounds.

    Learning Theory of Transformers: Local-to-Global Approximation via Softmax Partition of Unity

    This paper investigates the learning theory of Transformer networks for regression tasks on the compact Euclidean domain $[0,1]^d$ and $d$-dimensional compact Riemannian manifolds. We propose a novel constructive approximation framework for Transformers that builds local approxim…
