In recent years, neural-networks have demonstrated robust non-linear modeling capabilities and millisecond-scale inference at a comparatively small computational footprint, making them an attractive family of algorithms in this context. However, integration of these algorithms into the gravitational-wave astrophysics research ecosystem has proven non-trivial. Here, we present a machine learning-based pipeline for the detection of gravitational waves from compact binary coalescences (CBCs) designed to run in low-latency. We demonstrate this pipeline to have a fraction of the latency of traditional matched filtering search pipelines while achieving state-of-the-art sensitivity to higher-mass stellar binary black holes.  \nI. INTRODUCTION  \nGravitational-wave astronomy has developed rapidly since the first direct detection of gravitational waves from a binary black hole merger in 2015[1], with new detections now a common occurrence[2] . With the fourth observing run (O4) of the LIGO-Virgo-KAGRA (LVK) collaboration [3–5] already underway, and with future ground and space based detectors planned for various points in the next decade[6–8], ever more frequent discoveries of gravitational waves will enable follow-up observation of events across other cosmic messengers such as electromagnetic radiation and astrophysical neutrinos[9– 14] . The insights we gain in this era of multi-messenger astrophysics will directly correlate with the volume and diversity of data we are able to collect. Already, the first multi-messenger event, which included the gravitational wave event GW170817 [15], the gamma ray burst GRB170817A [16–19], and the kilonova AT2017gfo [20– 22] has led to a gold mine of new science.  \nWhile machine learning (ML) is ubiquitous in some areas of physics[23], it has only recently approached a stage of maturity in the gravitational-wave community. To date, there have been a number of machine learning models proposed for the detection of compact binary coalescences (CBCs); e.g.,[24–28]; but there are none currently running in O4[29](though, ML-based unmodeled gravitational-wave searches have seen production usage[30]) . This is both a product of well-known infrastructure hurdles separating the development and deployment of machine learning models[31], as well as a lack of standardized, astrophysically meaningful probes of the  \nsensitivity of these models in the face of non-stationary and transient background noise.  \nThe most well-modeled and frequently observed gravitational-wave events to date are the mergers of binary black hole (BBH) systems[2, 32 , 33] Their comparatively high number of confirmed detections has given us reasonable models of their population statistics, allowing for astrophysically ","cbCaiet9KyIX8L4q","https://ap.wps.com/l/cbCaiet9KyIX8L4q","pdf",905673,1,14,"English","en",105,"# Introduction\n## Multi-messenger astronomy and low-latency requirements\n## Machine learning maturity and integration challenges\n## Deep learning approach (Aframe) and motivation\n# Aframe algorithm overview\n## Performance metric\n## Datasets, training, and evaluation\n## Model longevity\n## Latency and computational requirements\n## Comparison with existing pipelines","[{\"question\":\"Why is low latency crucial for gravitational-wave detection in multi-messenger astronomy?\",\"answer\":\"Low latency preserves more time for follow-up observations across other messengers such as electromagnetic radiation and neutrinos.\"},{\"question\":\"What are the main obstacles to deploying machine-learning models in current gravitational-wave workflows?\",\"answer\":\"Infrastructure hurdles and the lack of standardized, astrophysically meaningful ways to evaluate sensitivity under non-stationary, transient background noise.\"},{\"question\":\"How does the proposed pipeline (Aframe) compare with traditional matched filtering?\",\"answer\":\"The pipeline runs with a fraction of the latency of traditional matched-filtering search pipelines while achieving state-of-the-art sensitivity for higher-mass stellar binary black holes.\"}]","A machine-learning pipeline for real-time detection of gravitational waves from compact binary coalescences -
