Question

The confusion matrix for a classification method with Class 1 and Class 0 is given below Refer to Exhibit 9-1. What is the percent overall error rate? A. 58.82% B. 43.25% C. 7.69% D. 36.67% Refer to Exhibit 9-1. What is the sensitivity rate? A. 7.69% B. 56.37% C. 42.18% D. 92.31% Refer to Exhibit 9-1. What is the precision percentage? A. 92.3% B. 54.55% C. 73.33% D. 58.82% Refer to Exhibit 9-1. What are the percent error rates for Class 1 and Class 0? A. 7.69% and 58.82%, respectively B. 36.67% and 43.25%, respectively C. 43.25% and 7.69%, respectively D. 7.6% and 36.67%, respectively Exhibit 9-2. The scatter chart below displays 6 observations of a training set plotted according to the values of 2 quantitative variables (x_1 and x_2 expressed in the same units that characterize the 6 observations. (The normalization of these values is not needed.). Three observations (#1, #2, #3) belong to Class 1, and the other three (#4, #5, #6) to Class 0. The chart also displays a new observation (#7) that must be classified using the k-NN method with the cutoff value of 0.5.

Explanation / Answer

1) total = 300

number of error = 10+100

110/ 300 =0.36666

option D) is correct
