how to identify the probability for bayesian network using pomegranate python?
Attached the code on google colab.
I want to identify the over written probability after training my model.
I trained my model using bayesian network. After training i defined the levels of probabiliy. now i need to check whether it is greater than…

How to assure that the covariance matrices are all positive definite in Pomigranate MultivariateGaussianDistribution
As in the ScikitLearn GaussianMixture model, reg_covar=1e-06 adds Non-negative regularization to the diagonal of covariance, which ensures covariance matrices are positive definite.
sklearn.mixture.GaussianMixture(n_components=1, *,…
