It is a method that calculates the Euclidean distance to split observations into k clusters in which each observation is attributed to the cluster with the nearest mean (cluster centroid). WebK-Means-Clustering Description: This repository provides a simple implementation of the K-Means clustering algorithm in Python. The goal of this implementation is to provide an easy-to-understand and easy-to-use version of the algorithm, suitable for small datasets. Features: Implementation of the K-Means clustering algorithm describe the test for proteins
