“…The goal of spectral/subspace clustering, which is a simple extension of traditional clustering, is to cluster data points that lie in a union of low-dimensional subspaces. Spectral clustering found a number of applications, as they are parts of more complex algorithms, like community detection algorithms (Makris, Pispirigos, & Rizos, 2020), film recommender systems for users (Cintia Ganesha Putri, Leu, & Seda, 2020), and algorithms to detect open-source software ecosystems (Liao, Wang, Liu, Zhang, Liu, & Zhang, 2019).…”
