论文摘要
我们证明了基于通用卷积的单杆对象检测模型的Yolov5模型的应用,在从当前生成干涉仪检测器的重力数据中检测二进制中子星(BNS)合并事件的任务。我们还基于用于模型训练,验证和测试步骤的大概波形模型对合成数据生成和准备任务的详尽说明。使用这种方法,我们实现平均平均精度($ \ text {map} _ {[0.50]} $)值为单个类验证数据集的0.945,对于测试数据集,高达0.978。此外,训练有素的模型成功地识别了Ligo H1检测器数据中的GW170817事件。 LIGO L1检测器数据也可以通过附加的预处理步骤进行识别,而无需在Inspiral的最后阶段消除大故障。 GW190425事件的检测不太成功,这证明了信噪比的性能退化。我们的研究表明,Yolov5模型是第一阶段检测警报管道的有趣方法,并且在整合到更复杂的管道中时,用于实时推断物理源参数。
We demonstrate the application of the YOLOv5 model, a general purpose convolution-based single-shot object detection model, in the task of detecting binary neutron star (BNS) coalescence events from gravitational-wave data of current generation interferometer detectors. We also present a thorough explanation of the synthetic data generation and preparation tasks based on approximant waveform models used for the model training, validation and testing steps. Using this approach, we achieve mean average precision ($\text{mAP}_{[0.50]}$) values of 0.945 for a single class validation dataset and as high as 0.978 for test datasets. Moreover, the trained model is successful in identifying the GW170817 event in the LIGO H1 detector data. The identification of this event is also possible for the LIGO L1 detector data with an additional pre-processing step, without the need of removing the large glitch in the final stages of the inspiral. The detection of the GW190425 event is less successful, which attests to performance degradation with the signal-to-noise ratio. Our study indicates that the YOLOv5 model is an interesting approach for first-stage detection alarm pipelines and, when integrated in more complex pipelines, for real-time inference of physical source parameters.
