摘要:

引力波是时空结构中以光速传播的涟漪。LIGO探测到引力波是天文学领域的重大突破。深度学习已经彻底改变了许多行业,包括医疗保健,金融和教育。深度学习技术也被探索用于检测引力波,以克服传统匹配滤波方法的缺点。然而,在一些研究中,神经网络的训练阶段是非常耗时的,并且需要具有大存储器的硬件设备来完成任务。为了减少训练用于探测引力波的神经网络所需的大量硬件资源和时间,我们制作了SpecGrav。利用二维卷积神经网络和噪声背景下的引力波谱图对双黑洞合并和双中子星合并产生的引力波进行了探测。我们的神经网络的训练阶段在2GB GPU上只有大约19分钟。

英文摘要:

Gravitational waves are ripples in the fabric of space-time that travel at the speed of light. The detection of gravitational waves by LIGO is a major breakthrough in the field of astronomy. Deep Learning has revolutionized many industries including health care, finance and education. Deep Learning techniques have also been explored for detection of gravitational waves to overcome the drawbacks of traditional matched filtering method. However, in several researches, the training phase of neural network is very time consuming and hardware devices with large memory are required for the task. In order to reduce the extensive amount of hardware resources and time required in training a neural network for detecting gravitational waves, we made SpecGrav. We use 2D Convolutional Neural Network and spectrograms of gravitational waves embedded in noise to detect gravitational waves from binary black hole merger and binary neutron star merger. The training phase of our neural network was of about just 19 minutes on a 2GB GPU.
