WebJun 12, 2024 · It is called ‘Gaussian’ classifier because of the assumption that p ( x y = c ) is Gaussian distribution. It is also known as ‘Mixture Gaussian’ and ‘Discriminant’ classifier. http://cs229.stanford.edu/section/cs229-gaussian_processes.pdf
WebFor this reason, we name this model as Gaussian Mixture Bayesian Nonparametric Kernel Learning using Spectral Representation (GaBaSR). Furthermore, to learn the Gaussian mixture, the proposed algorithm uses ideas proposed in [ 15 ], together with a different way to learn the kernel in the classification task.
