This paper presents a theoretical framework for understanding the attention mechanism within Transformer models by drawing connections to calculus of variations and Lagrangian optimization. The authors explore these concepts on the unit hyperspherical manifold and its tangent bundle, proposing methods that can be categorized as inexact due to projection-based techniques and epsilon-type perturbations. The research aims to analyze the attention mechanism as a flow map for tokens on a high-dimensional sphere and to broaden the mathematical lens for variational calculus in approximating contexts. AI
IMPACT Provides a novel mathematical perspective on the attention mechanism, potentially influencing future theoretical research in deep learning.
