Clustering is an unsupervised technique in which the set of similar data points is grouped together to form a cluster. A Cluster is said to be good if the intra-cluster (the data points within the same cluster) similarity is high and the inter-cluster (the data points outside the cluster) similarity is low. Clustering is the task of dividing the unlabeled data or data points into different clusters such that similar data points fall in the same cluster than those which differ from the others. In simple words, the aim …Database clustering is a process to group data objects (referred as tuples in a database) together based on a user defined similarity function. Intuitively, a cluster is a collection of data objects that are “similar” to each other when they are in the same cluster and “dissimilar” when they are in different clusters. Similarity can be ...Summary. Cluster analysis is a powerful technique for grouping data points based on their similarities and differences.
