Utilizing Gaussian mixture models in all-sky searches for short-duration gravitational wave bursts

Understand

Coherent WaveBurst is a generic, multidetector gravitational wave burst search based on the excess power approach.

• The coherent WaveBurst algorithm currently employed in the all-sky short-duration gravitational wave burst search uses a conditional approach on selected attributes in the multidimensional event attribute space to distinguish between noisy events from that of astrophysical origin.
• We have been developing a supervised machine learning approach based on the Gaussian mixture modeling to model the attribute space for signals as well as noise events to enhance the probability of burst detection [Gayathri et al.Phys.
