The development of big data era makes the application of clustering algorithms more and more widespread. but most current clustering algorithms are sensitive to noisy data and cannot identify datasets with complex structures such as non-convex shapes. To address this problem. a clustering algorithm for constructing connected graph with reverse nearest neighbor is proposed. https://www.roneverhart.com/AMS-Neve-1073SPX-Single-Preamp-and-EQ-p33827/
