Alberto From reading scikit-learn 's documentation, I learned that the implementation behind the DPGMM class uses variational inference instead of traditional Gibbs sampling. Nonetheless, while reading Edwin Chen's popular article ("Infinite Mixture Models wit

Yufeng I am really new to python and GMM. I recently learned GMM and tried to implement the code from here I have some problems running the gmm.sample() method: gmm16 = GaussianMixture(n_components=16, covariance_type='full', random_state=0)

mid-term plan There are two ways to specify noise levels for Gaussian Process Regression (GPR) in scikit-learn. The first way is to specify the parameter alpha in the constructor of the class GaussianProcessRegressor , which only adds values to the diagonal as
