Hierarchical Adaptive Clustering [PDF]

open access: yesInformatica, 2008
This paper studies an adaptive clustering problem. We focus on re-clustering an object set, previously clustered, when the feature set characterizing the objects increases. We propose an adaptive clustering method based on a hierarchical agglomerative approach, Hierarchical Adaptive Clustering (HAC), that adjusts the partitioning into clusters that was

Complementary hierarchical clustering [PDF]

open access: yesBiostatistics, 2007
When applying hierarchical clustering algorithms to cluster patient samples from microarray data, the clustering patterns generated by most algorithms tend to be dominated by groups of highly differentially expressed genes that have closely related expression patterns.

A semi-supervised hierarchical ensemble clustering framework based on a novel similarity metric and stratified feature sampling

open access: yesJournal of King Saud University: Computer and Information Sciences, 2023
Recently, both ensemble clustering and semi-supervised clustering have emerged as important paradigms of traditional clustering. Ensemble clustering seeks to integrate multiple clustering results from different methods or the same methods with different ...

Comparison of Unsupervised Machine Learning Approaches for Cluster Analysis to Define Subgroups of Heart Failure with Preserved Ejection Fraction with Different Outcomes

open access: yesBioengineering, 2022
Heart failure with preserved ejection (HFpEF) is a heterogenous condition affecting nearly half of all patients with heart failure (HF). Artificial intelligence methodologies can be useful to identify patient subclassifications with important clinical ...

Convex clustering: an attractive alternative to hierarchical clustering.

open access: yesPLoS Computational Biology, 2015
The primary goal in cluster analysis is to discover natural groupings of objects. The field of cluster analysis is crowded with diverse methods that make special assumptions about data and address different scientific aims.

RECURSIVE HIERARCHICAL CLUSTERING FOR HYPERSPECTRAL IMAGES [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
Partition based clustering techniques are widely used in data mining and also to analyze hyperspectral images. Unsupervised clustering only depends on data, without any external knowledge.

Belief Hierarchical Clustering [PDF]

open access: yes, 2014
In the data mining field many clustering methods have been proposed, yet standard versions do not take into account uncertain databases. This paper deals with a new approach to cluster uncertain data by using a hierarchical clustering defined within the belief function framework.

Neutrosophic Hierarchical Clustering Algoritms [PDF]

open access: yesNeutrosophic Sets and Systems, 2014
Interval neutrosophic set (INS) is a generalization of interval valued intuitionistic fuzzy set (IVIFS), whose the membership and non-membership values of elements consist of fuzzy range, while single valued neutrosophic set (SVNS) is regarded as ...

A Data-Driven Clustering Recommendation Method for Single-Cell RNA-Sequencing Data

open access: yesTsinghua Science and Technology, 2021
Recently, the emergence of single-cell RNA-sequencing (scRNA-seq) technology makes it possible to solve biological problems at the single-cell resolution.
