Summary

  • Building Machine Learning models is fun, but making sure we build the best ones is what makes a difference.
  • The ratio of correct positive predictions to the total positives examples.
  • In our case of predicting if a loan would default — It would be better to have a high Recall as the banks don’t want to lose money and would be a good idea to alarm the bank even if there is a slight doubt about defaulter.
  • The higher the area under the ROC curve (AUC), the better the classifier.
