New theory certifies transformer attention with quadratic bounds

Researchers have developed a new conic programming theory for certifying the attention mechanisms in transformer models. This theory addresses the NP-hard nature of certifying attention outputs under input perturbations, particularly due to the interaction between varying queries and keys. The new method provides a certificate with an error bounded quadratically by computable quantities, offering a tighter bound than linear propagation methods. Experiments on GPT-2 demonstrate the theory's effectiveness, achieving predicted accuracy against exact worst cases with a fixed query. AI

IMPACT Provides a more rigorous method for verifying the robustness of transformer models, potentially improving their reliability in critical applications.
