Sigmoid Function

  • takes in any value and outputs it to be between 0 and 1
  • in this case, we can set a cutoff point at 0.5
    - p <0.5 → 0 / p>=0.5 → 1

Evaluation

  • confusion matrix can be used
  • Accuracy : (True positive+True Negative)/total
  • Misclassification Rate : (False Positive + False Negative) / Total
