Deep spatio-temporal point processes: Advances and new directions

  • Spatio-temporal point processes (STPPs) are used to model discrete events distributed in time and space.
  • Traditional models often rely on parametric kernels, limiting their ability to capture heterogeneous, nonstationary dynamics.
  • Recent innovations integrate deep neural architectures to model the conditional intensity function or learn flexible, data-driven influence kernels.
  • The article discusses the development of the deep influence kernel approach, its components, applications in crime analysis, earthquake aftershock prediction, and sepsis prediction modeling, and promising directions for the field.
