WebbThe classifiers with CV suffixed to their names implement inbuilt cross-validation (like LogisticRegressionCV, RidgeClassifierCV etc). Some are ensemble and may take other classifiers in input arguments. Some classifiers like _QDA, _LDA are aliases for other classifiers and may be removed in next versions of scikit-learn. jerry fallwell speedoWebbHow To Predict Natural Language Sentiment Using A Naive Bayes Classifier by Mr. Data Science The Data Science Publication Medium Write Sign up Sign In 500 Apologies, but something went... jerry falwell 2022Webb@unutbu: Naive Bayes classifiers assumes independence of the features given the class.
