Seq2Slate issue

[20010404]

Hi. Can you please give me the source code of seq2slate algorithm alone? I have searched the online environment but only to find it in ReAgent. It could be really kind of you as I am at the start step of reranking models. I promise I will only use it for research. My email is deborahpyx010404@gmail.com.

Thanks for your help. I will look at the code carefully. So difficult for me now :)

Hi, Deborah

Regarding Seq2Slate - be aware that the current version doesn't implement paddings in the batch. The main problem is the last decoder layer (specifically autoregressive decoding); it requires a symmetrical decoder mask in purpose to properly form the distribution over items, excluding paddings. If your problem definition assumes sequences of different lengths, you should carefully implement this logic
