WebIn transformers, self-attention is entirely driven by the values in the image/feature with no limits on the context window. You can use any value in the global context based on its similarity with current cell/vector. This leads to different weights based on your position, data values and global context. 3. Reply. WebMar 13, 2024 · QKV是Transformer中的三个重要的矩阵，用于计算注意力权重。qkv.reshape(bs * self.n_heads, ch * 3, length)是将qkv矩阵重塑为一个三维张量，其中bs是batch size，n_heads是头数，ch是每个头的通道数，length是序列长度。split(ch, dim=1)是将这个三维张量按照第二个维度（通道数）分割成三个矩阵q、k、v，分别代表查询 ...

WebAttention (machine learning) In artificial neural networks, attention is a technique that is meant to mimic cognitive attention. The effect enhances some parts of the input data while diminishing other parts — the motivation being that the network should devote more focus to the small, but important, parts of the data. WebSep 13, 2024 · 具体来说，4-head self-attention 的实现方法是，将输入序列中的每一个元素与整个序列进行关系计算，并将计算出的关系按照一定的权重进行加权求和，得到一个新的向量，表示这个元素对应的注意力权重。这个过程在模型中重复进行 4 次，因此称为 4-head self-attention。
