WebApr 11, 2024 · The basic core concept of this study, which is based on the DFT operation and zero-padding, is an extended smoothing method for two-dimensional discrete data. The DFT operation has the characteristics of fast computation and transformation between the spatial domain and the wavenumber domain.
WebDensity-Based Clustering refers to unsupervised machine learning methods that identify distinctive clusters in the data, based on the idea that a cluster/group in a data space is a contiguous region of high point density, separated from other clusters by sparse regions. Web1 day ago · Various clustering algorithms (e.g., k-means, hierarchical clustering, density-based clustering) are derived based on different clustering standards to accomplish specific tasks ( Steinley, 2006; Dasgupta and Long, 2005; Ester et al., 1996 ). In this study, we utilize the DBSCAN algorithm to extract the phase-velocity dispersion curves.
