Prof Cheng is the world leading expert in the principles and practice of (Big) spatio-temporal data analytics. She has developed theories and methods to model and predict space-time processes by statistical and machine learning approaches and has first-hand experience of big data analytics in urban mobility, intelligent policing, retail business and hazard prevention.
Network and Graph-based SpaceTimeAI
This talk will propose to use networks (graphs) as the spatial structure to present space-time processes happening at places that are conventionally represented as spatial units: points, lines/networks, or polygon/areas/grids. These processes could be dense (everywhere) or sparse (only somewhere), such as flows on almost all roads or crimes only at some locations (many zero observations for sparse point data). This talk will show cases of applications in transport, crime and public health to demonstrate the strength of using networks and graph-based deep learning for space-time prediction and analysis.
Mark Birkin is Professor of Spatial Analysis and Policy in the School of Geography, University of Leeds. He has longstanding interests in mathematical modelling of urban and regional systems including geodemographics, microsimulation, agent-based modelling, and spatial decision-support systems.
