Mobility and Contact Networks Shape Epidemic Outcomes: A Large-Scale Agent-Based Modeling Study
Kuldip Singh Atwal, Emma Von Hoene, Hossein Amiri +3
The paper investigates how different assumptions about human mobility affect contact network structures and epidemic outcomes in a large-scale agent-based model of an urban populat…
Staypoint Detection from Noisy Trajectory Data [Experiment Paper]
Lance Kennedy, Hossein Amiri, Yueyang Liu +9
Detecting staypoints from raw trajectory data is fundamental to numerous spatial computing applications. This process transforms raw numeric sequences of geolocations into semantic…
Simulating Public Transit Fare Policies in NYC: An Efficient, Socioeconomic-Aware Framework
Parker Wischhover, Hossein Amiri, Kiara Ha +4
Designing equitable and effective public transit fare policies is challenging due to complex interactions among traveler behavior, multimodal networks, and socioeconomic heterogene…
PlaceRep: Geospatial Place Representation Learning from Large-Scale Point-of-Interest Data
Mohammad Hashemi, Hossein Amiri, Andreas Zufle
Learning effective representations of urban environments requires capturing spatial structure beyond fixed administrative boundaries. Existing geospatial representation learning ap…
Where Do We Poop? City-Wide Simulation of Defecation Behavior for Wastewater-Based Epidemiology
Hossein Amiri, Akshay Deverakonda, Yuke Wang +1
Wastewater surveillance, which regularly measures pathogen biomarkers in wastewater samples, is a valuable tool for monitoring infectious diseases circulating in communities. Yet,…
