WebJan 2, 2015 · Gaussian RBF kernels are non-parametric model which essentially means that the complexity of the model is potentially infinite because the number of analytic functions are infinite. Gaussian kernels are optimal (on smoothness, read more here - same author): A Gaussian Kernel is just a band pass filter; it selects the most smooth solution. WebFeb 5, 2024 · Gaussian distribution is a widely used continuous probabilistic representation, and it provides a useful way to estimate uncertainty in the world. We'll start by discussing the one-dimensional Gaussian distribution, and then move on to the multivariate Gaussian. Finally, we'll extend the concept to models that use mixtures of Gaussians.
