English(EN) Joint Subspace Sparse Attention for Efficient Long-Context Decoding

新的JSSA方法将LLM长上下文解码速度提升6.43倍

作者 PulseAugur 编辑部 · [2 个来源] ·

研究人员开发了一种新颖的联合子空间稀疏注意力（JSSA）方法，以提高大型语言模型长上下文解码的效率。JSSA通过学习共享的低维查询-键子空间以获得更好的排序，并采用无收集的索引注意力核来提高效率，从而解决了令牌级选择的挑战。该方法显著提高了解码吞吐量，在128K上下文的NVIDIA B200 GPU上实现了高达6.43倍的性能提升，同时保持了高推理准确性。 AI

影响 增强了LLM在长上下文任务中的效率，可能支持更复杂的应用并降低计算成本。
