We are delighted to announce that a team of PhD students from LSGI, led by Prof. Yang XU, has won first place at the ACM SIGSPATIAL Cup 2025 (GISCUP). The team—Mr. Guangyue LI, Mr. Yuxiao LUO, Mr. Shen LIANG, and Ms. Jinghan WANG—stood out among global competitors to earn this prestigious honor at the ACM SIGSPATIAL 2025 Annual Conference in Minneapolis, USA.
The ACM SIGSPATIAL Cup is a premier competition in geospatial AI. This year’s challenge, “Human Mobility Prediction in Multiple Cities,” required participants to forecast complex mobility trajectories across diverse metropolitan areas. To tackle the challenge of adapting to various urban layouts, the team developed the “HuMob Predictor” framework. Their innovative approach combined a multi-level encoding module, designed to capture intricate urban structures, with an incremental training strategy that progressively learns from simple patterns to complex dependencies.
The team’s solution demonstrated outstanding stability and performance during the official evaluation, setting a new benchmark for individual mobility prediction. This remarkable achievement underscores PolyU LSGI’s expertise in addressing complex spatiotemporal problems and advancing generalizable geospatial AI.
Congratulations to Prof. XU and the team!
