Self-supervised Graph-based Point-of-interest Recommendation

no code implementations22 Oct 2022 Yang Li, Tong Chen, Peng-Fei Zhang, Zi Huang, Hongzhi Yin

In order to counteract the scarcity and incompleteness of POI check-ins, we propose a novel self-supervised learning paradigm in \ssgrec, where the trajectory representations are contrastively learned from two augmented views on geolocations and temporal transitions.

Discovering Domain Disentanglement for Generalized Multi-source Domain Adaptation

1 code implementation11 Jul 2022 Zixin Wang, Yadan Luo, Peng-Fei Zhang, Sen Wang, Zi Huang

A typical multi-source domain adaptation (MSDA) approach aims to transfer knowledge learned from a set of labeled source domains, to an unlabeled target domain.
