K-means Clustering in Data Mining Code

K-means clustering is simple unsupervised learning algorithm developed by J. MacQueen in 1967 and then J.A Hartigan and M.A Wong in 1975.; In this approach, the data objects ('n') are classified into 'k' number of clusters in which each observation belongs to the cluster with nearest mean.

K-means Clustering Python Example Towards Data Science

K-Means Clustering is an unsupervised machine learning algorithm. In contrast to traditional supervised machine learning algorithms, K-Means attempts to classify data without having first been trained with labeled data. Once the algorithm has been run and the groups are defined, any new data can be easily assigned to the most relevant group.

K- Means Clustering Algorithm How It Works Analysis

K-Means clustering algorithm is defined as a unsupervised learning methods having an iterative process in which the dataset are grouped into k number of predefined non-overlapping clusters or subgroups making the inner points of the cluster as similar as possible while trying to keep the clusters at distinct space it allocates the data points to a cluster so that the sum of the squared

k-means clustering Wikipedia

k-means clustering is a method of vector quantization, originally from signal processing, that aims to partition n observations into k clusters in which each observation belongs to the cluster with the nearest mean (cluster centers or cluster centroid), serving as a prototype of the cluster.This results in a partitioning of the data space into Voronoi cells.
