Web11 de jan. de 2024 · Here we will focus on Density-based spatial clustering of applications with noise (DBSCAN) clustering method. Clusters are dense regions in the data space, separated by regions of the lower density of points. The DBSCAN algorithm is based on this intuitive notion of “clusters” and “noise”. The key idea is that for each point of a ...
