“…In recent years, researchers have gradually paid more attention to the use of machine learning to analyze massive amounts of seismic data Rouet-Leduc, Hulbert, Lubbers, Barros, Humphreys and Johnson (2017); Corbi, Sandri, Bedford, Funiciello, Brizzi, Rosenau and Lallemand (2019); Bergen, Johnson, Maarten and Beroza (2019); Mousavi and Beroza (2020). In addition, serval algorithms have been increasingly used to identify the microseismic events, such as extreme learning machines Zhang, Jiang, Li and Xu (2019), the Gaussian mixture model Wang, Tang, Ma, Wang and Li (2020), logistic regression Pu, Apel and Hall (2020), the random forest algorithm Provost, Hibert and Malet (2017), and neural network algorithms Xu, Zhang, Chen, Li and Liu (2021). Although these studies have laid the foundation for the development of microseismic data processing, there is still a large gap regarding the demand for efficient, accurate, and real-time identification of useful microseismic events for engineering applications.…”
