WEBFeb 22, 2017 · I want to use sklearn.mixture.GaussianMixture to store a gaussian mixture model so that I can later use it to generate samples or a value at a sample point using score_samples method. Here is an example where the components have the following weight, mean and covariances
Understanding Gaussian Mixture Models - Stack Overflow
WEBJan 19, 2017 · Here I first generate a sample distribution constructed from gaussians, then fit a gaussian mixture model to these data. Next, I want to calculate the probability for some given input. Conveniently, the scikit implementation offer the score_samples method to do just that. Now I am trying to understand these results.
Mixture of Gaussians using scikit learn mixture - Stack Overflow
WEBFeb 11, 2015 · I'd like to use sklearn.mixture.GMM to fit a mixture of Gaussians to some data, with results similar to the ones I get using R's "Mclust" package.
