Block-Sparse FlashAttention Top-k Selection for Long-Context Cross-Lingual Summarization

Abstract

Abstract: This report synthesises findings from 8 peer-reviewed papers addressing the following research question: How does Block-Sparse FlashAttention's top-k selection strategy compare to other block-sparse attention mechanisms in terms of accuracy and throughput when applied to cross-lingual summarization. 15 claims were extracted from source literature; 4 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 5.2/10. This report is a machine-generated literature synthesis and does not constitute original research.

Research Question

How does Block-Sparse FlashAttention's top-k selection strategy compare to other block-sparse attention mechanisms in terms of accuracy and throughput when applied to cross-lingual summarization tasks on the XSum benchmark with context lengths up to 128k?
