CausalPOI: Spatio-Temporal Graph-Based Causal Modeling for Cold-Start POI Check-in Forecasting
Summary
CausalPOI is a novel spatio-temporal graph-based causal representation learning framework designed for cold-start Point of Interest (POI) check-in forecasting. This framework addresses the challenge of predicting future check-in patterns for newly introduced POIs by modeling their temporal evolution and functional interactions within an urban spatial context. Unlike traditional methods that rely on proximity-based graphs and correlation, CausalPOI incorporates functional dependencies and causal effects of urban interventions. It utilizes a Spatio-Temporal Functional Interaction Graph to model semantic and spatial relationships, and constructs structurally aligned treatment and control graphs to simulate factual and counterfactual scenarios. Extensive experiments conducted on real-world SafeGraph datasets demonstrate CausalPOI's significant outperformance against state-of-the-art baselines, validating its effectiveness in spatio-temporal forecasting, semantic interaction modeling, and causal effect estimation, offering a more interpretable foundation for urban intervention analysis.
Key takeaway
For urban planners and commercial decision-makers evaluating new Points of Interest, CausalPOI offers a superior method for cold-start check-in forecasting. You should consider integrating causal modeling to move beyond correlation-based predictions, gaining more interpretable insights into functional dependencies and the true impact of urban interventions. This approach provides a robust foundation for data-driven planning and optimizing new POI placements.
