WebbIn scikit-learn there is a class CountVectorizer that converts messages in form of text strings to feature vectors. We can integrate this conversion with the model we are using (multinomial naive Bayes), so that the conversion happens automatically as part of the fit method. We achive this integration using the make_pipeline tool. [16]: WebbThe multinomial Naive Bayes classifier is suitable for classification with discrete features (e.g., word counts for text classification). The multinomial distribution normally requires integer feature counts. …
