Kimi Delta Attention Explained: From Quadratic to Linear Variants

By PulseAugur Editorial · [1 sources] ·

This article delves into the Kimi Delta Attention (KDA) mechanism, a sophisticated variant of linear attention. It traces the evolution from quadratic attention to KDA, explaining how KDA addresses the limitations of earlier linear attention models by focusing on error correction rather than direct value updates. The explanation uses bra-ket notation and mathematical derivations to illustrate the process, highlighting its use in modern models like Qwen and Kimi. AI

IMPACT Explains a novel attention mechanism that could improve efficiency and performance in large language models.
