The performance of Earth-based GW detectors is largely influenced by the ability of combating the low-frequency ambient seismic noise and other seismic influences. These tasks require multidisciplinary research in the fields of seismic sensing, signal processing, robotics, machine learning and mathematical modeling.
The working group 2, deals with acquisition, processing and interpretation of seismic data, with the goal of combating the seismic influences at GW detector site, using the multidisciplinary research, with a focus on advanced techniques available from state of the art machine learning algorithms.
WG2 is actively working on the following tasks
• Nonstationary signal analysis: Extraction of Useful Information from Noisy Signals; GW and seismic signal denoising; Time-Frequency Representations of seismic data.
• Deep learning for seismic time series: Rapid prediction of earthquake ground shaking intensity for VIRGO using ML; Intra-domain and cross-domain transfer learning for time series; Learning to Invert Pseudo-Spectral Data for Seismic Waveform Inversion.
• Newtonian noise detection and seismic sensor arrays: Analysis of seismic data from the Virgo network; Seismic networks at the ET candidate site in Sardinia; Seismic networks for machine learning, Advanced equipment (mobile seismic sensors, infrasound microphone…).
• Probabilistic robotics for seismology and GW detection: Gaussian and non-Gaussian processes for the characterization of Newtonian, seismic and other kinds of noises; Advanced information theoretic methods for multi-sensory fusion to drive the information gathering and motion planning (information theoretic measures, probabilistic graphical models, causal networks, dynamic programming…); Simultaneous localization and geographical fields mapping by means of network or swarms of autonomous mobile robots.
