Where Do Q, K, and V Come From in Attention Mechanisms?

In deep learning, especially in the field of natural language processing, the Attention mechanism has become a very important method. Its core idea is to allocate different weights based on the relevance of each element in the input sequence to the current element, thereby achieving dynamic focus on the input sequence. In the Attention mechanism, … Read more
