mclearn.performance.get_beta_parameters(confusion)[source]

Extract the beta parameters from a confusion matrix.

Parameters:confusion (array, shape = [n_classes, n_classes]) – Where entry c_{ij} is the number of observations in class i but are classified as class j.
Returns:parameters – Each tuple (alpha_i, beta_i) is the parameters of a Beta distribution that corresponds to class i.
Return type:array of tuples
