Model-based clustering algorithmTime series clusteringGiven a set of multivariate time series, the problem of clustering such data is concerned with the discovering of inherent groupings of the data according to how similar or dissimilar the time series are to each other. Existing time series ...

4. Research Model of College Students’ Classroom Concentration Based on Computer Statistical Analysis and Fuzzy Control The AdaBoost algorithm is a very effective sample learning algorithm, and it also has a good classification effect for training the human eye classifier and can quickly determine the...
Alignment and integration of complex networks by hypergraph-based spectral clustering Complex networks possess a rich, multiscale structure reflecting the dynamical and functional organization of the systems they model. Often there is a need... T Michoel,B Nachtergaele - 《Physical Review E》 被引...
We propose a novel model-based recursive-partitioning algorithm to navigate clusters in a beta mixture model. We present simulations that show that the method is more reliable than competing nonparametric clustering approaches, and is at least as reliable as conventional mixture model methods. We also...
We propose a model-based approach to clustering the edges of a network using a latent space model describing the features of both actors and latent environments. We derive a generalized EM algorithm for estimation and gradient-based Monte Carlo algorithms, and we demonstrate that the computational ...
Model-based clustering is a popular technique relying on the notion of finite mixture models that proved to be efficient in modeling heterogeneity in data. The underlying idea is to model each data group by a particular mixture component. This relationsh
EMCluster is an R package providing EM algorithms and several efficient initialization methods for model-based clustering of finite mixture Gaussian distribution with unstructured dispersion in both of unsupervised and semi-supervised learning. Installation EMCluster requires R version 3.0.0 or higher. R...
To infer population structure in this broad sample, we used a model-based clustering algorithm implemented in the computer program Structure version 2 [8, 9]. This algorithm uses multilocus genotype to identify a predetermined number (K) of clusters that have distinctive allele frequencies and assig...
a balanced model-based partitional clustering algorithm that produces clusters of comparable sizes and a hybrid model-based clustering approach that combines the advantages of partitional and hierarchical model-based algorithms.; I apply the framework and new clustering algorithms to cluster several ...
