General Attention Formula
The general attention mechanism maps a set of queries, keys, and values to an output. This output is calculated as a weighted sum of the value vectors, where the weights are determined by a compatibility function between the queries and keys. The matrix form of this operation is: . In this formula, , , and are the query, key, and value matrices, respectively. The term represents the attention weight matrix, which has dimensions of , where is the sequence length.
