1. IntroductionAcoustic emission (AE) has been extensively utilized as a distinctive non-destructive testing method in structural health monitoring and material performance analysis, with a research history spanning over 60 years in concrete engineering [1]. However, the inherent complexity of concrete materials and the diverse forms of structural configurations introduce considerable uncertainty into AE signals.
