Revisiting Mobility Modeling with Graph: A Graph Transformer Model for Next Point-of-Interest Recommendation

1 code implementation2 Oct 2023 Xiaohang Xu, Toyotaro Suzumura, Jiawei Yong, Masatoshi Hanai, Chuang Yang, Hiroki Kanezashi, Renhe Jiang, Shintaro Fukushima

Extracting distinct fine-grained features unique to each piece of information is difficult since temporal information often includes spatial information, as users tend to visit nearby POIs.

Is Self-Supervised Pretraining Good for Extrapolation in Molecular Property Prediction?

no code implementations16 Aug 2023 Shun Takashige, Masatoshi Hanai, Toyotaro Suzumura, LiMin Wang, Kenjiro Taura

In material science, the prediction of unobserved values, commonly referred to as extrapolation, is particularly critical for property prediction as it enables researchers to gain insight into materials beyond the limits of available data.

Time-Efficient and High-Quality Graph Partitioning for Graph Dynamic Scaling

no code implementations18 Jan 2021 Masatoshi Hanai, Nikos Tziritas, Toyotaro Suzumura, Wentong Cai, Georgios Theodoropoulos

In the case of distributed graph processing, changing the number of the graph partitions while maintaining high partitioning quality imposes serious computational overheads as typically a time-consuming graph partitioning algorithm needs to execute each time repartitioning is required.
