ST-PIL: Spatial-Temporal Periodic Interest Learning for Next Point-of-Interest Recommendation

no code implementations6 Apr 2021 Qiang Cui, Chenrui Zhang, Yafeng Zhang, Jinpeng Wang, Mingchen Cai

Specifically, in the long-term module, we learn the temporal periodic interest of daily granularity, then utilize intra-level attention to form long-term interest.

A new characterization of silting subcategories in the stable category of a Frobenius extriangulated category

no code implementations7 Dec 2020 YaJun Ma, Nanqing Ding, Yafeng Zhang, Jiangsheng Hu

We give a new characterization of silting subcategories in the stable category of a Frobenius extriangulated category, generalizing the result of Di et al. (J. Algebra 525 (2019) 42-63) about the Auslander-Reiten type correspondence for silting subcategories over triangulated categories.
