Recent advancements in remote sensing technologies and large-scale computing infrastructure have led to an unprecedented volume of spatio-temporal data in various fields. Integrating human-centered machine learning techniques with this data is crucial, but the quality of training data is not always guaranteed in the era of big spatio-temporal data. Furthermore, in urban computing applications, accurate predictive models alone may be insufficient, and providing efficient and interpretable predictions is equally important. To address these challenges, this presentation will showcase innovative research on developing robust and efficient spatio-temporal graph learning frameworks. These frameworks enable better analysis of large-scale spatio-temporal data for smart cities and improve the scalability of the models.
