Cover Story: Structural healthy monitoring systems generate a significant amount of data. This data is generally processed using machine learning based algorithms in order to ensure automatic damage detection. Supervised learning methods are the most used for that purpose. This study proposes a method for damage detection based on a modified version of the k-means algorithm, which is basically intended for unsupervised learning. View this paper.
