Main steps of our proposed method given a dataset of samples: 1 roughly cluster in order to swiftly make groups of similar sound samples. 2 Find the major cluster i.e. the cluster best representative of the tested structure. 3 Extract the regular model from this cluster, in this case, the centroid. 4 Use the previously found regular model as a scale, reference for the non-defective sample to conduct diagnosis on the whole dataset
