  1. So here I'm drawing what could be the result of decision tree learning.

  2. Where again red is my positive class and green's my negative class, and
  3. then giving you a whole bunch of data points.
  4. And in the mere counting exercise I want you just fill in the confusion matrix.
  5. Once again we have a actual class and a predicted class.
  6. The actual is on top.
  7. The predicted on the left.
  8. And we have once again the four different cases.
  9. So take a look at the right side and do your counts.
