Implementing multi-head attention
Before you dive in and begin building your own MultiHeadAttention class, you'll try out using the class to see how it transforms the query, key, and value matrices. Recall that these matrices are generated by projecting the input embeddings using linear transformations with learned weights.
query, key, and value matrices have already been created for you, and the MultiHeadAttention has been defined for you.
