WebCNB is an adaptation of the standard multinomial naive Bayes (MNB) algorithm that is particularly suited for imbalanced data sets. Specifically, CNB uses statistics from the complement of each class to compute the model’s weights. The inventors of CNB show empirically that the parameter estimates for CNB are more stable than those for MNB. WebJan 10, 2024 · The Naive Bayes algorithm has proven effective and therefore is popular for text classification tasks. The words in a document may be encoded as binary (word present), count (word occurrence), or frequency (tf/idf) input vectors and binary, multinomial, or Gaussian probability distributions used respectively.
