Harris’ Hawks Optimization-Tuned Density-based Clustering

open access: yesSukkur IBA Journal of Emerging Technologies, 2023
Clustering is a machine learning technique that groups data samples based on similarity and identifies outliers with distinct features. Density-based clustering outperforms other methods because it can handle arbitrary shapes of clustering distributions.

Boundary Detection-Based Density Peaks Clustering

open access: yesIEEE Access, 2019
Clustering algorithms have a very wide range of applications on data analysis, such as machine learning, data mining. However, data sets often have problems with unbalanced and non-spherical distribution.

Semi-Supervised Density Peaks Clustering Based on Constraint Projection

open access: yesInternational Journal of Computational Intelligence Systems, 2020
Clustering by fast searching and finding density peaks (DPC) method can rapidly identify the centers of clusters which have relatively high densities and high distances according to a decision graph. Various methods have been introduced to extend the DPC

Source-lens clustering and intrinsic-alignment bias of weak-lensing estimators [PDF]

open access: yes, 2013
We estimate the amplitude of the source-lens clustering bias and of the intrinsic-alignment bias of weak lensing estimators of the two-point and three-point convergence and cosmic-shear correlation functions.

ConDPC: Data Connectivity-Based Density Peak Clustering

open access: yesApplied Sciences, 2022
As a relatively novel density-based clustering algorithm, Density peak clustering (DPC) has been widely studied in recent years. DPC sorts all points in descending order of local density and finds neighbors for each point in turn to assign all points to ...

Efficient incremental density-based algorithm for clustering large datasets

open access: yesAlexandria Engineering Journal, 2015
In dynamic information environments such as the web, the amount of information is rapidly increasing. Thus, the need to organize such information in an efficient manner is more important than ever.

Generalized density clustering

open access: yes, 2010
We study generalized density-based clustering in which sharply defined clusters such as clusters on lower-dimensional manifolds are allowed. We show that accurate clustering is possible even in high dimensions.
