Clustering is the task of grouping a set of objects in such a way that similar objects lie within the same group (called cluster). These groups are not pre-defined beforehand, so it is an unsupervised task.
This “similarity” notion is vague enough to empower different uses. Popular notions of it include distance-based clusters, dense areas of data space, intervals or statistical distributions.
