Document Classification: how to boost your classifier

ADaBoost.M1 tries to improve step by step the accuracy of the classifier analyzing its behavior on training set. (Of course you cannot try to improve the classifier working with the test set!!).

  4. I calculated for each instance the frequency to find it in the doc;
  5. I weighted such TF-IDF considering also the distance among the…
