An Overlapping Subspace K-Means Clustering Algorithm [PDF]

open access: yesJisuanji gongcheng, 2020
Most of existing clustering algorithms for high-dimensional sparse data do not consider overlapping class clusters and outliers,resulting in unsatisfactory clustering results.Therefore,this paper proposes an overlapping subspace K-Means clustering ...

Genetic K-means algorithm [PDF]

open access: yesIEEE Transactions on Systems, Man and Cybernetics, Part B (Cybernetics), 1999
In this paper, we propose a novel hybrid genetic algorithm (GA) that finds a globally optimal partition of a given data into a specified number of clusters. GA's used earlier in clustering employ either an expensive crossover operator to generate valid child chromosomes from parent chromosomes or a costly fitness function or both.

Optimized K‐Means Algorithm [PDF]

open access: yesMathematical Problems in Engineering, 2014
The localization of the region of interest (ROI), which contains the face, is the first step in any automatic recognition system, which is a special case of the face detection. However, face localization from input image is a challenging task due to possible variations in location, scale, pose, occlusion, illumination, facial expressions, and clutter ...

An Incremental K-means algorithm [PDF]

open access: yesProceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2004
Data clustering is an important data exploration technique with many applications in engineering, including parts family formation in group technology and segmentation in image processing. One of the most popular data clustering methods is K-means clustering because of its simplicity and computational efficiency.

ck-means and fck-means: Two Deterministic Initialization Procedures for k-means Algorithm Using a Modified Crowding Distance

open access: yesActa Informatica Pragensia, 2023
This paper presents two novel deterministic initialization procedures for k-means clustering based on a modified crowding distance. The procedures, named ck-means and fck-means, use more crowded points as initial centroids.

A Modified K-means Algorithms - Bi-Level K-Means Algorithm [PDF]

open access: yesAdvances in Intelligent Systems Research, 2014
In this paper, a modified K-means algorithm is proposed to categorize a set of data into smaller clusters. K- means algorithm is a simple and easy clustering method which can efficiently separate a huge number of continuous numerical data with high-dimensions. Moreover, the data in each cluster are similar to one another.
