Performance Analysis and Architecture of a Clustering Hybrid Algorithm Called FA+GA-DBSCAN Using Artificial Datasets

open access: yesEntropy, 2022
Density-Based Spatial Clustering of Applications with Noise (DBSCAN) is a widely used algorithm for exploratory clustering applications. Despite the DBSCAN algorithm being considered an unsupervised pattern recognition method, it has two parameters that ...

Self-adaptive GA, quantitative semantic similarity measures and ontology-based text clustering [PDF]

open access: yes, 2008
As the common clustering algorithms use vector space model (VSM) to represent document, the conceptual relationships between related terms which do not co-occur literally are ignored.

Differential evolution-based transfer rough clustering algorithm

open access: yesComplex & Intelligent Systems, 2023
Due to well processing the uncertainty in data, rough clustering methods have been successfully applied in many fields. However, when the capacity of the available data is limited or the data are disturbed by noise, the rough clustering algorithms always

Ensemble Clustering Algorithm Based on Weighted Super Cluster

open access: yesJisuanji kexue yu tansuo, 2021
Most ensemble clustering algorithms use K-means to generate base clustering, but the result of base clustering is not good. And most ensemble clustering algorithms ignore the diversity of base clustering, treat base clustering equally, and generate the ...

Analysis of influencing factors on excellent teachers' professional growth based on DB-Kmeans method

open access: yesEURASIP Journal on Advances in Signal Processing, 2022
The Kmeans clustering algorithm is widely used for the advantages of simplicity and efficient operation. However, the lack of clustering centers in the algorithm usually causes incorrect category of some discrete points.

Cluster synchronization algorithms

open access: yesProceedings of the 2010 American Control Conference, 2010
This paper presents two approaches to achieving cluster synchronization in dynamical multi-agent systems. In contrast to the widely studied synchronization behavior, where all the coupled agents converge to the same value asymptotically, in the cluster synchronization problem studied in this paper, we require that all the interconnected agents to ...

Robust structure low-rank representation in latent space [PDF]

open access: yes, 2019
Subspace clustering algorithms are usually used when processing high-dimensional data, such as in computer vision. This paper presents a robust low-rank representation (LRR) method that incorporates structure constraints and dimensionality reduction for ...
