Attention 机制很像人类看图片的逻辑,当我们看一张图片的时候,我们并没有看清图片的全部内容,而是将注意力集中在了图片的焦点上。. 大家看下面这张图自行体会:. 对于CV中早期的 ... WebThe attention applied inside the Transformer architecture is called self-attention. In self-attention, each sequence element provides a key, value, and query. For each element, we perform an attention layer where based on its query, we check the similarity of the all sequence elements' keys, and returned a different, averaged value vector for ... free songs to hear
