Gaussian Mixture Models Algorithm Based on Density Peaks Clustering [PDF]

open access: yesJisuanji kexue, 2021
Due to the existence of a large number of sample data which obey the Gaussian distribution,GMM (Gaussian mixture models) is used to cluster these sample data and get more accurate clustering results.In general,EM algorithm(expectation maxi-mization ...

Deep Gaussian mixture models [PDF]

open access: yesStatistics and Computing, 2017
Deep learning is a hierarchical inference method formed by subsequent multiple layers of learning able to more efficiently describe complex relationships. In this work, Deep Gaussian Mixture Models are introduced and discussed. A Deep Gaussian Mixture model (DGMM) is a network of multiple layers of latent variables, where, at each layer, the variables ...

An Improved Mixture Model of Gaussian Processes and Its Classification Expectation–Maximization Algorithm

open access: yesMathematics, 2023
The mixture of experts (ME) model is effective for multimodal data in statistics and machine learning. To treat non-stationary probabilistic regression, the mixture of Gaussian processes (MGP) model has been proposed, but it may not perform well in some ...

Gaussian Mixture Models in R

open access: yesThe R Journal, 2023
  Gaussian mixture models (GMMs) are widely used for modelling stochastic problems. Indeed, a wide diversity of packages have been developed in R. However, no recent review describing the main features offered by these packages and comparing their performances has been performed.

Model Selection for Gaussian Mixture Models [PDF]

open access: yesStatistica Sinica, 2017
This paper is concerned with an important issue in finite mixture modelling, the selection of the number of mixing components. We propose a new penalized likelihood method for model selection of finite multivariate Gaussian mixture models. The proposed method is shown to be statistically consistent in determining of the number of components. A modified

Quantum-like Gaussian mixture model [PDF]

open access: yesSoft Computing, 2021
Abstract A new concept of a quantum-like mixture model is introduced. It describes the mixture distribution with the assumption that a point is generated by each Gaussian at the same time. The decision boundary of a quantum-like mixture Gaussian corresponds as well to the separation of probabilities for the switching Kalman filter. The quantum-
