WebMay 24, 2024 · The three major steps involved in spectral clustering are: constructing a similarity graph, projecting data onto a lower-dimensional space, and clustering the data. Given a set of points S in a higher-dimensional space, it can be elaborated as follows: 1. Form a distance matrix 2. Transform the distance matrix into an affinity matrix A WebIn this paper, we present the new clustering algorithm DBSCAN relying on a density-based notion of clusters which is designed to discover clusters of arbitrary shape.
