K-means algorithm is is one of the simplest and popular unsupervised machine learning algorithms, that solve the well-known clustering problem, with no pre-determined labels defined, meaning that we don’t have any target variable as in the case of supervised learning. It is often referred to as Lloyd’s algorithm.
