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 ...
Journal of Machine Learning Research, 14(Apr):1175-1179. 5. GPfit:jstatsoft.org/article/v 这是个基于R的toolbox,唯一一个本人没有亲自用过的,不过这个似乎是我可以在网上找到的一个比较完善的一个R代码包。当然之前提到的Nicolas Durrande,他的github上也有一个Gaussian processes in TensorFlow via R,...

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...
