A Unified Model for Spatio-Temporal Prediction Queries with Arbitrary Modifiable Areal Units

1 code implementation10 Mar 2024 Liyue Chen, Jiangyi Fang, Tengfei Liu, Shaosheng Cao, Leye Wang

Spatio-Temporal (ST) prediction is crucial for making informed decisions in urban location-based applications like ride-sharing.

UCTB: An Urban Computing Tool Box for Spatiotemporal Crowd Flow Prediction

1 code implementation7 Jun 2023 Liyue Chen, Di Chai, Leye Wang

To address these issues, we design and implement a spatiotemporal crowd flow prediction toolbox called UCTB (Urban Computing Tool Box), which integrates multiple spatiotemporal domain knowledge and state-of-the-art models simultaneously.

A Data-driven Region Generation Framework for Spatiotemporal Transportation Service Management

no code implementations5 Jun 2023 Liyue Chen, Jiangyi Fang, Zhe Yu, Yongxin Tong, Shaosheng Cao, Leye Wang

In this paper, we propose RegionGen, a data-driven region generation framework that can specify regions with key characteristics (e. g., good spatial semantic meaning and predictability) by modeling region generation as a multi-objective optimization problem.
