Class scipy.maxentropy.bigmodelв¶ a maximum-entropy (exponential-form) model on a large sample space. the model expectations are not computed exactly (by summing or feature vector. feature vector is the most important concept in implementing a classifier. a good feature vector directly determines how successful your classifier

"maximum entropy" is synonymous with "least informative". you wouldn't want a classifier that was least informative. it is in reference to how the priors are established. in statistics, multinomial logistic regression is a classification method that generalizes logistic regression to multiclass problems,
