Question

The following confusion matrix represents the functional performance of a classifier. Which ONE of the following is the correct calculation for the accuracy of the classifier?

Options

  • A60 / (60 + 20) * 100% = 75%
  • B60 / (60 + 9) * 100% = 87%
  • C2 * (60 / (60 + 20) * 60 / (60 + 9)) / (60 / (60 + 20) + 60 / (60 + 9)) * 100% = 80%
  • D(60 + 11) / (60 + 11 + 20 + 9) * 100% = 71%
