arXiv:2510.05688v2 Announce Type: replace Abstract: State-of-the-art sparse attention methods for reducing decoding latency fall into two main categories: approximate top-$k$ (and its extension, top-$p$) and recently introduced sampling-based estimation. However, these approaches are fundamentally limited in their ability to approximate full attention: they fail to provide consistent approximations across heads and query vectors and, most critically, lack guarantees on approximation quality, limiting their practical deployment. We observe that top-$k$ and random sampling are complementary: top
The continuous drive for more efficient and robust AI models, especially in large language models, necessitates advancements in fundamental mechanisms like attention, which is a core component.
Improved sparse attention methods with verifiable guarantees can significantly enhance the efficiency, reliability, and deployment of complex AI systems, reducing computational costs and increasing model stability.
The development of 'verified sparse attention' introduces a new standard for approximation quality and consistency, potentially leading to more trustworthy and performant AI architectures.
