Sorted by: 1. As per your understanding, multi-head attention is multiple times attention over some data. But on contrast, it isn't implemented by multiplying the set of weights into number of required attention. Instead, you rearrange the weight matrices corresponding to the number of attentions, that is reshape to the weight-matrix.
