Witryna29 lis 2024 · For Gaussian Mixture Models, in particular, we’ll use 2D Gaussians, meaning that our input is now a vector instead of a scalar. This also changes our parameters: the mean is now a vector as well! The mean represents the center of our data so it must have the same dimensionality as the input. The variance changes less … Witryna13 kwi 2024 · 1 Introduction.
