Local Self Attention 的注意力矩阵(左)和关联图示(右) 局部自注意力则是约束每个元素只与前后 k 个元素以及自身有关联。 OpenAI 的稀疏自注意力,是 Atrous Self Attention 和 Local Self Attention 的结合体。每个元素只与相对距离不超过 k 的、相对距离为 k, 2k, 3k,…的元素有关联。 Sparse Self Attention...
matrix 2.引入u和v,在计算self-attention时,由于query所有位置对应的query向量是一样的,因此不管的query位置如何,对不同单词的attention偏差应保持相同。 总结...的vanilla Transformer 的基础上,引进了2个新的技术来覆盖上面的2个缺点:循环机制和相对位置编码( Recurrence Mechanism and Relative Positional FlyAI资讯:...
具体来说:(1)Transformer 的核心是 self-attention,因此作者将从 self-attention 或其变体如何以及何时进行跨模态交互的角度来比较现有的多模态预训练 Transformer 模型。 (2)从几何拓扑的角度考虑,self-attention 通过将每个 token 的嵌入作为图的节点,帮助 Transformers 本质上在与各种模态兼容的模态无关 pipeline 中...
在Attention机制上，稀疏注意力机制如OpenAI的Atrous Self Attention和Local Self Attention旨在减少运算时间和显存占用，Multi-query attention和Grouped-query Attention则通过减少内存占用来提高效率，FlashAttention则从GPU底层数据存储的角度出发，优化内存使用和计算速度。并行Transformer block如PaLM中的预归一化...
I don’t make cupcakes very often.Rarely.As in four times a year maybe. I have nothing against cupcakes. I am as picky with them as I am about any small bite I make, bake or eat. They’d better have a higher interestingness to frosting ratio for me to pay attention. In about ever...
Coffee And Vanilla: With Haruka Fukuhara, Shôgo Hama, Dôri Sakurada, Yûki Ogoe. Tokyo student, Shiroki Risa meets businessman, Fukami Hiroto and they fall in love, but his dark past threatens their relationship.
一、Vanilla Transformer(对网络结构没有很大调整,主要是引入了辅助损失,基于transformer的语言模型)Character-Level Language Modeling with Deeper Self-Attention 指的是字符级语言模型 源自论文 Character…

girl who is being spanked, not as a complete, integrated unit of personhood but rather as a series of discrete body parts, like some medieval poet praising his lady-love bit by bit, with her hair, nose, lips and eyebrows (along with many others) each singled out for laudatory attention....
