DECODE: DilatEd COnvolutional neural network for Detecting Extreme-mass-ratio inspirals

no code implementations31 Aug 2023 Tianyu Zhao, Yue Zhou, Ruijun Shi, Zhoujian Cao, Zhixiang Ren

The detection of Extreme Mass Ratio Inspirals (EMRIs) is intricate due to their complex waveforms, extended duration, and low signal-to-noise ratio (SNR), making them more challenging to be identified compared to compact binary coalescences.

Space-based gravitational wave signal detection and extraction with deep neural network

1 code implementation15 Jul 2022 Tianyu Zhao, Ruoxi Lyu, He Wang, Zhoujian Cao, Zhixiang Ren

Space-based gravitational wave (GW) detectors will be able to observe signals from sources that are otherwise nearly impossible from current ground-based detection.

Improved deep learning techniques in gravitational-wave data analysis

1 code implementation9 Nov 2020 Heming Xia, Lijing Shao, Junjie Zhao, Zhoujian Cao

We point out that CNN models are robust to the variation of the parameter range of the GW waveform.

Gravitational wave signal recognition of O1 data by deep learning

1 code implementation30 Sep 2019 He Wang, Zhoujian Cao, Xiaolin Liu, Shichao Wu, Jian-Yang Zhu

Our adjusted convolutional neural network admits comparable accuracy and efficiency of signal recognition as other deep learning works published in the literature.

Reduced-order surrogate models for scalar-tensor gravity in the strong field and applications to binary pulsars and GW170817

1 code implementation1 Jul 2019 Junjie Zhao, Lijing Shao, Zhoujian Cao, Bo-Qiang Ma

We investigate the scalar-tensor gravity of Damour and Esposito-Far\`ese (DEF), which predicts non-trivial phenomena in the nonperturbative strong-field regime for neutron stars (NSs).
