how to implement target attention in this framework

[LeiShenVictoria]

In DeepInterestNetwork, there is a target attention between a candidate feature (one column) and a sequence feature, how to implement this target attention in this repo, which can be considered as an attention between a column in deep part (candidate) and the text part (sequence) i guess...
Thanks a lot

Hey @LeiShenVictoria

So I have not read the Deep Interest Network paper, I will, maybe I can incorporate some ideas to the library.

As of right now, the only thing "kind-of" similar you would have here are the attention weights of the models.

All model components that are based on attention mechanisms have an attribute called attention_weights: see here

I will have a look to the paper Deep Interest Network paper asap and see if I can come up with a quick answer that is more helpful :)

Hi, thanks for your reply.
One more question is that how to implement the embedding-sharing operation for a candidate feature and a sequence feature.
