新的稀疏注意力方法提高了 Transformer 处理长上下文的效率 · 跟踪 4 个来源

作者 PulseAugur 编辑部 · [5 个来源] ·

研究人员正在开发新方法来提高 Transformer 语言模型的效率，尤其是在处理长上下文方面。一种名为 BF1 的方法，通过确定性的块对齐稀疏注意力机制对现有模型进行改造，与密集注意力相比，显著加快了预填充时间并提高了训练困惑度。另一种方法侧重于使用稀疏注意力策略对模型进行微调，使其能够适应并优于使用精确注意力训练的模型，名为 KeysAndValues 的开源库促进了这些长上下文推理和微调任务。此外，还开发了一种名为 SparsePR 的无训练稀疏注意力方法，通过减少注意力计算来加速视频 Transformer，同时保持生成质量。 AI

影响 稀疏注意力的这些进步可以显著降低计算成本并提高大型语言模型的效率，从而在视频生成等领域实现更广泛的应用和新功能。
