Unsupervised K-Means Clustering Algorithm

open access: yesIEEE Access, 2020
The k-means algorithm is generally the most known and used clustering method. There are various extensions of k-means to be proposed in the literature. Although it is an unsupervised learning to clustering in pattern recognition and machine learning, the

Stop using the elbow criterion for k-means and how to choose the number of clusters instead [PDF]

open access: yesSIGKDD Explorations, 2022
A major challenge when using k-means clustering often is how to choose the parameter k, the number of clusters. In this letter, we want to point out that it is very easy to draw poor conclusions from a common heuristic, the "elbow method".

How to Use K-means for Big Data Clustering? [PDF]

open access: yesPattern Recognition, 2022
K-means plays a vital role in data mining and is the simplest and most widely used algorithm under the Euclidean Minimum Sum-of-Squares Clustering (MSSC) model. However, its performance drastically drops when applied to vast amounts of data.

Oversampling for Imbalanced Learning Based on K-Means and SMOTE [PDF]

open access: yesInformation Sciences, 2017
Learning from class-imbalanced data continues to be a common and challenging problem in supervised learning as standard classification algorithms are designed to handle balanced class distributions. While different strategies exist to tackle this problem,

Improving Scalable K-Means++

open access: yesAlgorithms, 2020
Two new initialization methods for K-means clustering are proposed. Both proposals are based on applying a divide-and-conquer approach for the K-means‖ type of an initialization strategy. The second proposal also uses multiple lower-dimensional subspaces

Scalable k-means++

open access: yesProceedings of the VLDB Endowment, 2012
Over half a century old and showing no signs of aging, k -means remains one of the most popular data processing algorithms. As is well-known, a proper initialization of k -means is crucial for obtaining a good final solution.
