Hearing the Signal through the Static: Real-time Noise Reduction in the Hunt for Binary Black Holes and other Gravitational Wave Transients

Real-time gravitational wave searches are plagued by non-stationary noise. The first a binary neutron star merger - had a delayed alert because we had to deal with data quality issues. We use machine learning to classify noise in real-time in based on auxiliary information like seismometers, magnetometers, etc.
