窗口注意力提供了一个部分解决方案,但当排除初始tokens时,其性能骤降。认识到这些tokens作为“attention sinks”的作用,我们引入了StreamingLLM——一个简单而高效的框架,使LLMs能够在不进行微调的情况下处理无限的文本。通过添加attention sinks和最近的tokens,StreamingLLM可以有效地对多达400万个tokens的文本进行建模。我...
简单来说,从技术方面来看,StreamingLLM就是: StreamingLLM = (attention sink) + (sliding window kv cache) 参考文献:Efficient Streaming Language Models with Attention Sinks 多轮对话场景属于一种streaming application,需要实现较长的交互,即需要具备超长文本的记忆和生成能力,主要存在两方面的挑战: (1) 在decodi...
- `attention_sinks`通过修改滑动窗口注意力机制,可以在不重新训练的情况下将LLMs的训练长度扩展到任意长度。 - 在benchmark测试中,`attention_sinks`的VRAM使用量保持恒定,处理超过窗口大小的文本时仍能保持流畅性。 - 使用`attention_sinks`加载的模型在连续提示下的流畅性表现良好,但对于某些模型仍可能存在流畅性问...
研究团队通过大量实验发现,在长上下文推理任务中,只有一小部分注意力头,即 “检索头”,需要对全部 token 进行关注,以获取上下文中的关键信息。而大多数注意力头,即 “流式头”,只需关注最近的 token 和注意力汇点(Attention Sinks),不需要存储全部的历史 KV 状态。 图1 展示了在 Llama-2-7B 模型上使用全注意...
我已经发布了attention_sinks Python模块,它可以作为transformers API的直接替代。这个Python模块支持使用Llama, Mistral, Falcon, MPT和GPT-NeoX (Pythia)架构的所有模型,使用方法如下: fromattention_sinksimportAutoModel model=AutoModel.from_pretrained("mistralai/Mistral-7B-Instruct-v0.1",device_map="auto") ...
StreamingLLM addresses this by retaining only the most recent tokens and attention sinks, discarding intermediate tokens. This enables the model to generate coherent text from recent tokens without a cache reset — a capability not seen in earlier methods. Is the context window of LLMs expanded?
