MQA是Transformer作者之一Noam Shazeer在19年就提出来的一种改进,一直没受到关注,最近的llama2在用MQA才被很多人关注;原始的MHA就是每个,下图可以很清晰地看明白; MQA(Multi-Query Attention,Fast Transformer Decoding: One Write-Head is All You Need)是多查询注意力的一种变体,也是用于自回归解码的一种注意力机...
而事实上,这种类似的方法最先提出于Multi-Query Attention,其是一种极端的策略,即假设K和V都只有一组仅仅对Q进行多头计算。对比图下所示: 以上便是LLM在推理过程中,关于Attention算子的全部介绍。在后续章节中,将会以LLama模型为例子,介绍llm的完整推理流程和一些模型参数的量化分析 ...

DeepSeek pays great attention to compliance and has not purchased any non-compliant GPUs, so it should have few chips. The way the United States uses GPUs is too extravagant. DeepSeek focused all its efforts on a single goal and subsequently gave up many things, such as multimodality. Deep...

We had some extra time before starting the Salkantay Trek, so we decided to book the 2 day Ica and Paracas tour. It was AMAZING. Ica and Huacachina were so fun that I always mention this tour to people who are planning to travel to Peru. H...
