Average sensitivity distance and runtime are measured using one month of blinded test data. Best machine learning methods reach up to 95% of matched-filtering sensitivity for simulated Gaussian noise at FAR of one per month, while real-noise performance leads to 70% and improves again at higher FAR.","First machine learning gravitational-wave search mock data challenge  \nMarlin B.

For this challenge, participating groups had to identify gravitational-wave signals from binary black hole mergers of increasing complexity and duration embedded in progressively more realistic noise. The final of the 4 provided datasets contained real noise from the O3a observing run and signals up to a duration of 20 s with the inclusion of precession effects and higher order modes. We present the average sensitivity distance and run-time for the 6 entered algorithms derived from 1 month of test data unknown to the participants prior to submission. Of these, 4 are machine learning algorithms. We find that the best machine learning based algorithms are able to achieve up to 95% of the sensitive distance of matched-filtering based production analyses for simulated Gaussian noise at a false-alarm rate (FAR) of one per month. In contrast, for real noise, the leading machine learning search achieved 70% . For higher FARs the differences insensitive distance shrink to the point where select machine learning submissions outperform traditional search algorithms at FARs ≥ 200 per month on some datasets. Our results show that current machine learning search algorithms may already be sensitive enough in limited parameter regions to be useful for some production settings. To improve the state-of-the-art, machine learning algorithms need to reduce the false-alarm rates at which they are capable of detecting signals and extend their validity to regions of parameter space where modeled searches are computationally expensive to run. Based on our findings we compile a list of research areas that we believe are the most important to elevate","cbCaijpnASrv3dW1","https://ap.wps.com/l/cbCaijpnASrv3dW1","pdf",4293921,1,24,"English","en",105,"# Introduction\n## Gravitational-wave observations and observing runs\n## Matched filtering and search methods","[{\"question\":\"What was the goal of the First Machine Learning Gravitational-Wave Search Mock Data Challenge?\",\"answer\":\"Participating groups had to identify gravitational-wave signals from binary black hole mergers with increasing complexity and duration, embedded in progressively more realistic noise.\"},{\"question\":\"What does the final dataset in the challenge contain?\",\"answer\":\"It uses real noise from the O3a observing run and includes signals up to 20 s, incorporating precession effects and higher order modes.\"},{\"question\":\"How did machine learning algorithms perform compared with matched filtering?\",\"answer\":\"For simulated Gaussian noise at a false-alarm rate of one per month, the best machine learning algorithms reached up to 95% of the sensitive distance of matched-filtering production analyses.
