Question

A
is a group of data points that are close together?

Answer 1

A **cluster** is a group of data points that are close together. In data analysis and machine learning, clustering refers to the task of grouping a set of objects in such a way that objects in the same group (or cluster) are more similar to each other than to those in other groups. Clusters are often identified through various algorithms, such as k-means or hierarchical clustering.
