This activity focuses on the evaluation of binary classification models using confusion matrix. In model 1, students will learn the table of confusion, which organizes the prediction results in a 2 by 2 matrix. In model 2, students will summarize a group of evaluation quantities based on the confusion matrix, including precision, recall, FPR, and accuracy. Lastly, students will compare the difference between type I and type II errors.
