Embedding of user (named after `u_emb`) seem to be unused in DIN model #6

Both variable i_emb and h_emb are irrelevant to embedding vector u_emb, while u_emb is assigned to hist (attention result). It's strange to define user embedding vector without using it.

I would appreciate it if you explain it in detail. Thanks

We did not use the u_emb in this paper. Only 'hist' of users are used to represent users. https://github.com/zhougr1993/DeepInterestNetwork/issues/3
