Plot the ROC curve for both M1 and M2. (You should plot them on the same graph.) Which model do you think is better? Explain your reasons.
You are asked to evaluate the performance of two classification models, M1
and M2. The test set you have chosen contains 26 binary attributes, labeled
as A through Z.
Table 5.5 shows the posterior probabilities obtained by applying the models to
the test set. (Only the posterior probabilities for the positive class are shown).
As this is a two-class problem, P(?)=1 ? P(+) and P(?|A, . . . , Z)=1 ?
P(+|A, . . . , Z). Assume that we are mostly interested in detecting instances
from the positive class.
The ROC curve for M1 and M2 are shown in the Figure 5.5.The ROC curve for M1 and M2 are shown in the Figure 5.5.
M1 is better, since its area under the ROC curve is larger than the area
under ROC curve for M2.
