Spatial-temporal Forecasting for Regions without Observations

1 code implementation19 Jan 2024 Xinyu Su, Jianzhong Qi, Egemen Tanin, Yanchuan Chang, Majid Sarvi

Our key insight is to learn from the locations that resemble those in the region of interest, and we propose a selective masking strategy to enable the learning.

Urban Region Representation Learning with Attentive Fusion

no code implementations7 Dec 2023 Fengze Sun, Jianzhong Qi, Yanchuan Chang, Xiaoliang Fan, Shanika Karunasekera, Egemen Tanin

Our model is powered by a dual-feature attentive fusion module named DAFusion, which fuses embeddings from different region features to learn higher-order correlations between the regions as well as between the different types of region features.
