Interpretable Spatio-Temporal Point Processes

Event models for complex temporal and spatial dynamics, with interpretability kept in view.

Summary

I work on point process models for event data where the goal is not only forecasting, but also understanding dynamics, stress-testing models, and supporting downstream scientific reasoning.

Research Question

What kinds of point process models remain interpretable while still being expressive enough for realistic spatio-temporal event data?

Methodology

  • Neural and physics-informed point process models
  • Benchmark design for spatio-temporal pattern complexity
  • Counterfactual analysis for event-generating processes

Key Contributions

  • Surveys and organizes the design space of neural spatio-temporal point processes
  • Builds evaluation frameworks for comparing event-model complexity
  • Studies counterfactual behavior and physically structured event models
