“…• Kbest: is an approach that selects the k best attributes based on a statistical measure, such as the analysis of variance (ANOVA) used in this study. By defining a value for k, it is possible to choose the k most significant features, which have a more relevant impact on the model's prediction [38,39]; • Random Forest (RF): is a technique that can be applied not only for building classification and regression models but also as a practical feature selection tool [40]. Random Forest performs several independent decision trees, each using different subsets of attributes and random samples from the data set.…”

“…, 2007; Vagnoli et al. , 2017; Alves and Cury, 2023). More specifically, the basic idea of them is that the damage in a structure leads to changes of its physical properties such as stiffness and mass, which alter the structure's dynamic characteristics described by structural modal parameters, mainly including natural frequencies, mode shapes (called displacement modes) and so on (Su et al.…”

“…Vibration-based damage localization methods have been developed rapidly in recent years, which are non-destructive and fast and easy to implement (Avci et al, 2021;Catbas et al, 2013;Katunin et al, 2015;Zhao et al, 2007;Vagnoli et al, 2017;Alves and Cury, 2023). More specifically, the basic idea of them is that the damage in a structure leads to changes of its physical properties such as stiffness and mass, which alter the structure's dynamic characteristics described by structural modal parameters, mainly including natural frequencies, mode shapes (called displacement modes) and so on (Su et al, 2016;Chaudhuri, 2008;Roy and Chaudhuri, 2013).…”

“…Notwithstanding the many procedures that can reduce ambient effects, further efforts are still needed to improve the damage assessment tools for practical applications (Wang et al 2022). Therefore, several contributions have been proposed by researchers, including different signal processing techniques to analyze and extract relevant information from raw dynamic data (Cardoso et al 2019a, Alves and Cury 2023.…”
