AERO: Entropy-Guided Attention for Private LLM Inference

Entropy-guided attention for efficient private LLM inference

Abstract

Private inference for language models is bottlenecked by nonlinear operations, motivating architectures that reduce expensive nonlinear components while preserving model quality. AERO studies the entropy dynamics induced by reducing transformer nonlinearities and identifies two failure modes: entropy collapse in deeper layers and entropic overload in earlier layers. It introduces entropy-guided attention and hierarchical entropy regularization to stabilize attention behavior while improving the efficiency of private LLM inference.

I study nonlinear representation dynamics in large language models, focusing on how nonlinearities, architecture, and optimization jointly shape representational geometry, scaling behavior, and usable computational capacity.
