K-Means clustering is one of the most widely used unsupervised machine learning algorithms that form clusters of data based on the similarity between data instances. In this guide, we will first take a look at a simple example to understand how the K-Means algorithm works before implementing it using Scikit-Learn.k-Means clustering is perhaps the most popular clustering algorithm. It is a partitioning method dividing the data space into K distinct clusters. It starts out with randomly-selected K cluster centers (Figure 4, left), and all data points are assigned to the nearest cluster centers (Figure 4, right).

Clustering algorithms allow data to be partitioned into subgroups, or clusters, in an unsupervised manner. Intuitively, these segments group similar observations together. Clustering algorithms are therefore highly dependent on how one defines this notion of similarity, which is often specific to the field of application. ...
