WebDec 28, 2024 · 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. 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 WebClustering—an unsupervised machine learning approach used to group data based on similarity—is used for work in network analysis, market segmentation, search results grouping, medical imaging, and anomaly detection.
