WebFeb 11, 2024 · Viewed 65 times 1 I read from a paper that Naive Bayes using IG is the best model for text classification where the dataset is small and has few positives. However, I'm not too sure how to code this specific model using Python. Would this be user TF or Scikit learn and then adjusting a parameter? machine-learning naivebayes Share WebMultinomial Naïve Bayes (MultinomialNB): This type of Naïve Bayes classifier assumes that the features are from multinomial distributions. This variant is useful when using discrete data, such as frequency counts, and it is typically applied within natural language processing use cases, like spam classification. ...
