大语言模型解码的时候,对于每个batch来讲,输入的seq就是1,这个时候attention的计算可以特别优化,我们经常调用mmha这个内核来进行计算。 mmha同时也是cuda新手上手的一个较好的例子 Paddle的mmha代码地址 大家都知道 cahce k的shape是[batch, num_head, max_len , head_dim] cahce v的shape是[batch, num_head,...

Enter multi-head attention (MHA) — a mechanism that has outperformed both RNNs and TCNs in tasks such as machine translation. By using sequence similarity, MHA possesses the ability to more efficiently model long-term dependencies. Moreover, masking can be employed to ensure that the MHA ...
Self Attention:考虑对于文章自身的每个单词而言重要的信息 ; Masked Attention:只考虑当前及过去的文本信息的重要性,不考 虑未来的文本信息的重要性; Multi-Head Attention :考虑对于同一词语的不同含义重要的信息,再 将结果“组合”起来。 发布于 2023-09-18 15:45・IP 属地广东 ...

The proposed model, called the Multi-head Attention-based Masked Sequence Model (MAMSM), uses a multi-headed attention mechanism and mask training approach to learn different states corresponding to the same voxel values. Additionally, it combines cosine similarity and task ...
🐛 Describe the bug I was developing a self-attentive module using nn.MultiheadAttention (MHA). My goal was to implement a causal mask that enforces each token to attend only to the tokens before itself, excluding itself, unlike the stand...

Multi-head channel attention and masked cross-attention mechanisms are employed to emphasize the importance of relevance from various perspectives in order to enhance significant features associated with the text description and suppress non-essential features unrelated to the textual information.
