Efficient Construction of Nonlinear Models over Normalized Data
Zhaoyue Chen, Nick Koudas, Zhe Zhang +1
Machine Learning (ML) applications are proliferating in the enterprise. Relational data which are prevalent in enterprise applications are typically normalized; as a result, data h…
Distributed Processing of k Shortest Path Queries over Dynamic Road Networks
Ziqiang Yu, Xiaohui Yu, Nick Koudas +4
The problem of identifying the k-shortest paths (KSPs for short) in a dynamic road network is essential to many location-based services. Road networks are dynamic in the sense that…
Top-k queries over digital traces
Yifan Li, Xiaohui Yu, Nick Koudas
Recent advances in social and mobile technology have enabled an abundance of digital traces (in the form of mobile check-ins, association of mobile devices to specific WiFi hotspot…
MPE: A Mobility Pattern Embedding Model for Predicting Next Locations
Meng Chen, Xiaohui Yu, Yang Liu
The wide spread use of positioning and photographing devices gives rise to a deluge of traffic trajectory data (e.g., vehicle passage records and taxi trajectory data), with each r…
TTDM: A Travel Time Difference Model for Next Location Prediction
Qingjie Liu, Yixuan Zuo, Xiaohui Yu +1
Next location prediction is of great importance for many location-based applications and provides essential intelligence to business and governments. In existing studies, a common…
TraLFM: Latent Factor Modeling of Traffic Trajectory Data
Meng Chen, Xiaohui Yu, Yang Liu
The widespread use of positioning devices (e.g., GPS) has given rise to a vast body of human movement data, often in the form of trajectories. Understanding human mobility patterns…
