Brief description of the k-means algorithm

WebThe working of the AHC algorithm can be explained using the below steps: Step-1: Create each data point as a single cluster. Let's say there are N data points, so the number of clusters will also be N. Step-2: Take two closest data points or clusters and merge them to form one cluster. So, there will now be N-1 clusters. WebK-Means clustering algorithm is defined as an unsupervised learning method having an iterative process in which the dataset are grouped into k number of predefined non-overlapping clusters or subgroups, making the …
