# Efficient gravitational-wave glitch identification from environmental data through machine learning

@article{Colgan2020EfficientGG, title={Efficient gravitational-wave glitch identification from environmental data through machine learning}, author={Robert E. Colgan and K. Rainer Corley and Yenson Lau and Imre Bartos and John N. Wright and Zsuzsanna Marka and Szabolcs M{\'a}rka}, journal={Physical Review D}, year={2020}, volume={101}, pages={102003} }

The LIGO observatories detect gravitational waves through monitoring changes in the detectors' length down to below ${10}^{\ensuremath{-}19}\text{ }\text{ }\mathrm{m}/\sqrt{\mathrm{Hz}}$ variations---a small fraction of the size of the atoms that make up the detector. To achieve this sensitivity, the detector and its environment need to be closely monitored. Beyond the gravitational-wave data stream, LIGO continuously records hundreds of thousands of channels of environmental and instrumental…
