Towards welfare-oriented recommendations in activity-travel behavior
Ekin Ugurel, Takahiro Yabe
While mainstream recommender systems (RS) rely on diverse heuristics to rank alternatives, they generally lack a principled account of user welfare (i.e., whether accepting the rec…
On Predicting Sociodemographics from Mobility Signals
Ekin Uğurel, Cynthia Chen, Brian H. Y. Lee +1
Inferring sociodemographic attributes from mobility data could help transportation planners better leverage passively collected datasets, but this task remains difficult due to wea…
Location-Based Service (LBS) Data Quality Metrics and Effects on Mobility Inference
Xinhua Wu, Yanchao Wang, Ekin Ugurel +3
Today, GPS-equipped mobile devices are ubiquitous, and they generate Location-Based Service (LBS) data, which has become a critical resource for understanding human mobility. Howev…
Comparing Fairness of Generative Mobility Models
Daniel Wang, Jack McFarland, Afra Mashhadi +1
This work examines the fairness of generative mobility models, addressing the often overlooked dimension of equity in model performance across geographic regions. Predictive models…
Event detection from novel data sources: Leveraging satellite imagery alongside GPS traces
Ekin Ugurel, Steffen Coenen, Minda Zhou Chen +1
Rapid identification and response to breaking events, particularly those that pose a threat to human life such as natural disasters or conflicts, is of paramount importance. The pr…
Time-Varying Transition Matrices with Multi-task Gaussian Processes
Ekin Ugurel
In this paper, we present a kernel-based, multi-task Gaussian Process (GP) model for approximating the underlying function of an individual's mobility state using a time-inhomogene…
