Clustering algorithms form groupings in such a way that data within a group (or cluster) have a higher measure of similarity than data in any other cluster. Various similarity measures can be used, including Euclidean, probabilistic, cosine distance, and correlation. Most unsupervised learning methods are a form of cluster analysis.

Clustering is the assignment of objects to homogeneous groups (called clusters) while making sure that objects in different groups are not similar. Clustering is considered an unsupervised task as it aims to describe the hidden structure of the objects. Each object is described by a set of characters called features.One of the most commonly used techniques of unsupervised learning is clustering. As the name suggests, clustering is the act of grouping data that shares similar characteristics. In machine learning, clustering is used when there are no pre-specified labels of data available, i.e. we don’t know what kind of groupings to create.The learning techniques for clustering can be classified into supervised, semi-supervised, and un-supervised learning.
