Boosting the Efficiency of Parametric Detection with Hierarchical Neural Networks

no code implementations23 Jul 2022 Jingkai Yan, Robert Colgan, John Wright, Zsuzsa Márka, Imre Bartos, Szabolcs Márka

Various approaches have been proposed for improving the efficiency of the detection scheme, with hierarchical matched filtering being an important strategy.

Detecting and Diagnosing Terrestrial Gravitational-Wave Mimics Through Feature Learning

no code implementations9 Mar 2022 Robert E. Colgan, Zsuzsa Márka, Jingkai Yan, Imre Bartos, John N. Wright, Szabolcs Márka

As engineered systems grow in complexity, there is an increasing need for automatic methods that can detect, diagnose, and even correct transient anomalies that inevitably arise and can be difficult or impossible to diagnose and fix manually.

Architectural Optimization and Feature Learning for High-Dimensional Time Series Datasets

no code implementations27 Feb 2022 Robert E. Colgan, Jingkai Yan, Zsuzsa Márka, Imre Bartos, Szabolcs Márka, John N. Wright

As our ability to sense increases, we are experiencing a transition from data-poor problems, in which the central issue is a lack of relevant data, to data-rich problems, in which the central issue is to identify a few relevant features in a sea of observations.

Generalized Approach to Matched Filtering using Neural Networks

no code implementations8 Apr 2021 Jingkai Yan, Mariam Avagyan, Robert E. Colgan, Doğa Veske, Imre Bartos, John Wright, Zsuzsa Márka, Szabolcs Márka

Moreover, we show that the proposed neural network architecture can outperform matched filtering, both with or without knowledge of a prior on the parameter distribution.

Outflow Bubbles from Compact Binary Mergers Embedded in Active Galactic Nuclei: Cavity Formation and the Impact on Electromagnetic Counterparts

no code implementations3 Mar 2021 Shigeo S. Kimura, Kohta Murase, Imre Bartos

We propose a novel scenario for possible electromagnetic (EM) emission by compact binary mergers in the accretion disks of active galactic nuclei (AGNs).

How to search for multiple messengers -- a general framework beyond two messengers

no code implementations8 Oct 2020 Doğa Veske, Zsuzsa Márka, Imre Bartos, Szabolcs Márka

Quantification of the significance of a candidate multi-messenger detection of cosmic events is an emerging need in the astrophysics and astronomy communities.

Optimal Gravitational-wave Follow-up Tiling Strategies Using a Genetic Algorithm

1 code implementation10 Mar 2020 Nihar Gupte, Imre Bartos

The identification of electromagnetic emission from gravitational-wave sources typically requires multiple follow-up observations due to the limited fields-of-view of follow-up observatories compared to the poorly localized direction of gravitational waves.
