WebThe self-attention model is a normal attention model. The query, key, and value are generated from the same item of the sequential input. In tasks that try to model sequential data, positional encodings are added prior to this input. The output of this block is the attention-weighted values. WebSelf-Attention helps the model to interact within itself. ... Create the context vector by computing the weighted sum of attention weights and encoder’s outputs.
