  • A confusion matrix for Reuters-21578.For example, 14 documents from grain were incorrectly assigned to wheat. Adapted from Picca et al. (2006) . An important tool for analyzing the performance of a classifier for classes is the confusion matrix .
  • In our look at predictive modeling tools so far, we focused on decision trees which are a form of supervised learning. Supervised learning broadly describes a type of machine learning algorithm that uses a known dataset to make predictions.
  • So this is an example of a confusion matrix, we can really understand the types of mistakes we made and we can interpret those. And this is a really important thing to do in classification
