Dr. Guojie Song: Network Representation Learning

Abstract: Feature engineering is one of the most important parts of machine learning task. As a most universal format of data existence, such as social network, information network etc, information networks have been widely studied within a broad scope of machine learning. Network Representation Learning (NRL) aims to project network nodes (or other entities) into a low-dimensional vector space while preserving general proximity between nodes, and has become a hot topic in data mining and machine learning. In this talk, I will first overview the basic concepts of NRL, and give an introduction about our recent advancements in such field, such as tag embedding, domain adaptive network embedding, and landmark based network embedding etc.

BiographyGuojie Song is an associate professor in the School of Electronics Engineering and Computer Science at Peking University. His research interests mainly include data mining and machine learning on network data, such as social network analysis, transportation network analysis etc. He has published 100+ papers, and more than 50+ paper published at leading journals and conferences, including TKDE, TPDS, TITS, TKDD, AAAI, IJCAI, CIKM, ICDM etc. He served as PC member and Senior PC member of AI related top conferences. His research results have received three awards from ministry and provinces in China, such as the first prize of Science and Technology award of China Highway Society (2012, 2013) and the Second Prize of Shanxi Science and Technology Award (2012).

Dr. Senzhang Wang: AI Empowered Spatio-Temporal Data Mining for Smart City: Challenges, Solutions, and Applications

Abstract:

With the fast development of various positioning techniques such as Global Position System (GPS), mobile devices and remote sensing, spatio-temporal data generated in urban areas has become increasingly available nowadays. Mining valuable knowledge from spatio-temporal data is critically important for better design of smart city applications, such as human mobility monitoring, smart transportation, urban planning, public safety, and environmental management. As the number, volume and resolution of spatio-temporal datasets increase rapidly, traditional data mining methods, especially statistics-based methods for dealing with such data are becoming overwhelmed. Recently, with the great success of AI techniques, especially deep learning methods, various AI techniques have been widely applied in analyzing rich spatio-temporal data generated in urban areas. In this tutorial, I will present our recent research on AI empowered spatio-temporal data mining. First, I will introduce the new challenges and opportunities of applying AI techniques to address various spatio-temporal data mining tasks in general. Then I will summarize a general framework to show the pipeline of AI empowered spatio-temporal data mining, followed by several examples illustrating how AI techniques including both shallow models and deep learning models can be utilized in the applications of demand-supply prediction in on-demand services, urban traffic prediction and urban crowd flow prediction. Finally, I will conclude the limitations of current research and point out future research directions.
