blockcluster: An R Package for Model-Based Co-Clustering [PDF]

open access: diamondJournal of Statistical Software, 2017
Simultaneous clustering of rows and columns, usually designated by bi-clustering, coclustering or block clustering, is an important technique in two way data analysis.

Model-Based Clustering of Mixed Data With Sparse Dependence

open access: yesIEEE Access, 2023
Mixed data refers to a mixture of continuous and categorical variables. The clustering problem with mixed data is a long-standing statistical problem. The latent Gaussian mixture model, a model-based approach for such a problem, has received attention ...

Model-Based Clustering

open access: yes, 2019
Mixture models extend the toolbox of clustering methods available to the data analyst. They allow for an explicit definition of the cluster shapes and structure within a probabilistic framework and exploit estimation and inference techniques available for statistical models in general.

Model-based clustering for populations of networks [PDF]

open access: yes, 2020
Until recently obtaining data on populations of networks was typically rare. However, with the advancement of automatic monitoring devices and the growing social and scientific interest in networks, such data has become more widely available.

Estimation of the Number of Endmembers in Hyperspectral Images Using Agglomerative Clustering

open access: yesRemote Sensing, 2020
Many tasks in hyperspectral imaging, such as spectral unmixing and sub-pixel matching, require knowing how many substances or materials are present in the scene captured by a hyperspectral image.

Summarizing Finite Mixture Model with Overlapping Quantification

open access: yesEntropy, 2021
Finite mixture models are widely used for modeling and clustering data. When they are used for clustering, they are often interpreted by regarding each component as one cluster. However, this assumption may be invalid when the components overlap.

Seasonal Dynamics of Soil Fungal and Bacterial Communities in Cool-Temperate Montane Forests

open access: yesFrontiers in Microbiology, 2019
Both fungal and bacterial communities in soils play key roles in driving forest ecosystem processes across multiple time scales, but how seasonal changes in environmental factors shape these microbial communities is not well understood. Here, we aimed to

teigen: An R Package for Model-Based Clustering and Classification via the Multivariate t Distribution

open access: yesJournal of Statistical Software, 2018
The teigen R package is introduced and utilized for model-based clustering and classification. The tEIGEN family of mixtures of multivariate t distributions is formed via an eigen-decomposition of the component covariance matrices and subsequent ...

Model Based Clustering for Mixed Data: clustMD [PDF]

open access: yes, 2015
A model based clustering procedure for data of mixed type, clustMD, is developed using a latent variable model. It is proposed that a latent variable, following a mixture of Gaussian distributions, generates the observed data of mixed type.
