Gaussian mixture model of heart rate variability. [PDF]

open access: yesPLoS ONE, 2012
Heart rate variability (HRV) is an important measure of sympathetic and parasympathetic functions of the autonomic nervous system and a key indicator of cardiovascular condition.

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-

Entropy-Based Anomaly Detection for Gaussian Mixture Modeling

open access: yesAlgorithms, 2023
Gaussian mixture modeling is a generative probabilistic model that assumes that the observed data are generated from a mixture of multiple Gaussian distributions. This mixture model provides a flexible approach to model complex distributions that may not

Optimal Transport for Gaussian Mixture Models [PDF]

open access: yesIEEE Access, 2019
We present an optimal mass transport framework on the space of Gaussian mixture models, which are widely used in statistical inference. Our method leads to a natural way to compare, interpolate and average Gaussian mixture models. Basically, we study such models on a certain submanifold of probability densities with certain structure. Different aspects

Reinforcement Learning with a Gaussian mixture model [PDF]

open access: yesThe 2010 International Joint Conference on Neural Networks (IJCNN), 2010
Recent approaches to Reinforcement Learning (RL) with function approximation include Neural Fitted Q Iteration and the use of Gaussian Processes. They belong to the class of fitted value iteration algorithms, which use a set of support points to fit the value-function in a batch iterative process.

Continuous Gaussian mixture modeling [PDF]

open access: yes, 1997
When the projection of a collection of samples onto a subset of basis feature vectors has a Gaussian distribution, those samples have a generalized projective Gaussian distribution (GPGD). GPGDs arise in a variety of medical images as well as some speech recognition problems.

Supervoxel Segmentation with Voxel-Related Gaussian Mixture Model

open access: yesSensors, 2018
Extended from superpixel segmentation by adding an additional constraint on temporal consistency, supervoxel segmentation is to partition video frames into atomic segments.

Regression with Gaussian Mixture ModelsApplied to Track Fitting

open access: yesInstruments, 2020
This note describes the application of Gaussian mixture regression to track fitting with a Gaussian mixture model of the position errors. The mixture model is assumed to have two components with identical component means.
