Urban Computing with City Dynamics

报告题目:Urban Computing with City Dynamics




报告内容:Urban computing is emerging as a concept where every sensor, device, person, vehicle, building, and street in the urban areas can be used as a component to probe city dynamics to further enable city-wide computing for serving people and their cities. Urban computing aims to enhance both human life and urban environment smartly through a recurrent process of sensing, mining, understanding, and improving. Urban computing also aims to deeply understand the nature and sciences behind the phenomenon occurring in urban spaces, using a variety of heterogeneous data sources reflecting city dynamics, such as traffic flows, human mobility, geographic and map data, environment, energy consumption, populations, and economics. In this talk, we will present our recent research on urban computing with city dynamics, introducing innovative application scenarios and the technology for integrating and mining heterogeneous city dynamics, such as, finding smart driving directions based on taxi trajectories, identify different functional regions (e.g., residential and commercial areas) in urban spaces using both POIs and human mobility, gleaning the problematic city configurations, and anomaly detection in road traffic flows (these examples have been published in top-tier conferences and journals recently, such as KDD, UbiComp, ICDE).
