How to generate unclicked sequence for a user?

[xiaochenwang94]

For the temporal view in your paper, you use clicked ad sequence and unclicked ad sequence. In your third dataset in Section 3.1, News feed advertising datasets, I think the clicked sequence is ads that a user clicked in the past few days. But for unclicked sequence, do you regard it as a sequence or just sampled impression ads without sequence aspect.

Thanks in advance.

In DSTN, we do not treat clicked ads / unclicked ads as sequences. We use the attention mechanism to aggregate each type of auxiliary ads. Unclicked ads are sampled impression ads without sequence aspect.
