“…Adachi et al [88] applied three data-mining techniques (i.e., hypothesis testing, discriminant Data-driven techniques are gaining in popularity since they are -as can be seen in Figure 13-model-free methods. Several features (indices, criteria) are generated in the time, frequency, time-frequency domain, and/or envelope spectrum features, which can usually be physically interpreted, or statistical features, which cannot be physically interpreted [84]. Different techniques from different disciplines are commonly used for data-driven FDD, including techniques from (digital) signal processing, cluster analysis, data mining, statistical pattern recognition, modern artificial intelligence (i.e., machine learning and deep learning), and image processing [84,85].…”
