The methodology involved applying a Generalized Linear Model (GLM) as the traditional regression approach and comparing its performance with two machine learning techniques: Random Forest (RF) and Gaussian Mixture Model (GMM). The GLM yielded an R2 value of 0.72. In contrast, RF and GMM ...

The Gaussian mixture model (GMM) is a parametric probabilistic model that assumes all data points are generated from a mixture of a finite number of Gaussian distributions. From: Advances in Mathematics for Industry 4.0, 2021 About this pageSet alert ...
We propose using a Gaussian Mixture Model (GMM) as reverse transition operator (kernel) within the Denoising Diffusion Implicit Models (DDIM) framework, which is one of the most widely used approaches for accelerated sampling from pre-trained Denoising Diffusion Probabilistic Models (DDPM). Specificall...
A Gaussian Mixture Model (GMM) is a parametric probability density function represented as a weighted sum of Gaussian component densities. GMMs are commonly used as a parametric model of the probability distribution of continuous measurements or features in a biometric system, such as vocal-tract rel...
