Motivation for x_context

[neverfox]

I am curious about the motivation for this step, as I couldn't anything about it in See et al., though I might have just missed it.

Yes in the paper it is not mentioned anywhere but the code has it.

I get the paper where similar kind of attention mechanism is used.

Order Matters: Sequence to sequence for sets

Thanks a lot for this work!
I have a question about when do you update this context. During training, as far as I understand, seems to be ok. However, during decoding, in the abisee code they seem to update the context before using it in lstm:

And then also update it after the call to lstm.

Thanks for pointing this out. You are right. I have updated my code, I still need to re-run the experiments though. I will update the result after that. Here is the commit:

By the way I am thinking about experimenting with transformer network for this task and verify speed and accuracy tradeoff. Let me know if you want to collaborate.
