Continuous-Time Sequential Recommendation with Temporal Graph Collaborative Transformer

1 code implementation14 Aug 2021 Ziwei Fan, Zhiwei Liu, Jiawei Zhang, Yun Xiong, Lei Zheng, Philip S. Yu

Therefore, we propose to unify sequential patterns and temporal collaborative signals to improve the quality of recommendation, which is rather challenging.

Modeling Sequences as Distributions with Uncertainty for Sequential Recommendation

1 code implementation11 Jun 2021 Ziwei Fan, Zhiwei Liu, Lei Zheng, Shen Wang, Philip S. Yu

We use Elliptical Gaussian distributions to describe items and sequences with uncertainty.

Augmenting Sequential Recommendation with Pseudo-Prior Items via Reversely Pre-training Transformer

1 code implementation2 May 2021 Zhiwei Liu, Ziwei Fan, Yu Wang, Philip S. Yu

We firstly pre-train a transformer with sequences in a reverse direction to predict prior items.
