WebJan 7, 2015 · DBSCAN does not "initialize the centers", because there are no centers in DBSCAN. Pretty much the only clustering algorithm where you can assign new points to the old clusters is k-means (and its many variations). Because it performs a "1NN classification" using the previous iterations cluster centers, then updates the centers. WebMay 24, 2024 · DBSCAN also known as Density-Based Spatial Clustering Application with Noise is an unsupervised machine learning algorithm that forms the clusters based upon the density of the data points or how close the data is. As a result, the points which are outside the dense regions are excluded and considered as the noisy points or outliers.
