WebApr 22, 2024 · DBSCAN algorithm. DBSCAN stands for density-based spatial clustering of applications with noise. It is able to find arbitrary shaped clusters and clusters with noise (i.e. outliers). The main idea behind DBSCAN is that a point belongs to a cluster if it is close to many points from that cluster. There are two key parameters of DBSCAN: WebThe baseline methods that we consider are based on a greedy-based approach and a well-known density-based clustering algorithm, DBSCAN .
