新的ReTopK方法加速了LLM的长上下文注意力

研究人员开发了ReTopK,一种提高Transformer模型长上下文注意力效率的新颖方法。该技术通过重用过去的注意力决策来加速识别相关键值对的过程,从而降低计算成本。ReTopK在128K上下文长度下实现了超过3倍的注意力计算加速,同时仅带来极小的困惑度增加。该方法在PG19和LongBench等基准测试中表现强劲,优于其他近似注意力方法。 AI

影响 加速了LLM在长上下文中的推理,可能降低计算成本,并支持具有更大上下文窗口的模型得到更广泛的应用。

    召回再排序:相似度引导的 Top-$K$ 重用以实现高效长上下文注意力

    arXiv:2607.27692v1 Announce Type: new Abstract: Top-$K$ sparse attention reduces the cost of Softmax and value aggregation by attending to only a small subset of key--value (KV) entries. However, identifying this subset still requires scoring the current query against the full KV…
