United Nations CTBTO 999-999999

The Comprehensive Test Ban Treaty (CTBT) bans nuclear explosions on earth. It includes a global monitoring system of seismic, hydroacoustic, infrasound, and radionuclide detectors. We are developing a new approach to solve the monitoring problem using probabilistic inference over a complete generative model of events and signals. Early results indicate substantial improvement over the current system's sensitivity and accuracy.
