As far as I understand the multi head attention it's just computing different K,Q,V for the same input by passing it through different linear transformations. Result is we get different output which we finally combine to create a single contextual embedding for each of the input tokens. The idea behind segmenting it into multiple head is that each part learns some different contextual information. However, at the end it's only generating a
