## Data Mining - Clustering

2010-4-17 · • Clustering is a process of partitioning a set of data (or objects) into a set of meaningful sub-classes, called clusters. • Help users understand the natural grouping or structure in a data set. • Clustering: unsupervised classification: no predefined classes. • Used either as a stand-alone tool to get insight into data

## Clustering Algorithm (DBSCAN)

2017-4-21 · Clustering Algorithm Clustering is an unsupervised machine learning algorithm that divides a data into meaningful sub -groups, called clusters. The subgroups are chosen such that the intra -cluster differences are minimized and the inter- cluster differences are maximized. The very definition of a ‘cluster’ depends on the application.
