Big Data Intelligence Group on SmartCity (BIGSCity)

The Big Data Intelligence Group on SmartCity research group (BIGSCity) aims to study data-driven science and technologies of making cities smarter and more intelligence. The research interests of BIGSCity include urban computing, spatio-temporal data mining, interpretable machine learning, and data visualization. BIGSCity has published more than 70 paper in prestigious conferences and journals in data mining, artificial intelligence and network communications. The technologies developed by BIGSCity have been applied in many real-world applications such as urban planning, intelligent transportation and health services. Tens of millions of population living in Beijing, Tianjin, Shenzhen, Wuxi, and Chengdu are benefited from these technologies.

LibCity: An Open Library for Traffic Prediction

LibCity (阡陌) is a unified, comprehensive and extensible library for traffic prediction, which provides researchers with a credible experimental tool and a convenient development framework. It collected 29 spatial-temporal datasets and reproduced 42 traffic prediction models, covering 4 mainstream tasks of traffic prediction. LibCity provides an important tool for researchers to use, explore and develop traffic prediction models, which will continuously contribute to the standardization and reproducibility in the field of traffic prediction. read more
