A classification study involving several classifiers was carried out. After training and the usual validation step, the following table shows results for classifiers tried. In below, classifiers are identified as M1, M2 and so on. Specificity Sensitivity M1 0.83 0.79 M2 0.93 0.69 M3 0.73 0.89 M4 0.47 0.45 M5 0.04 0.15 M6 0.14 0 M7 0.33 0.6 M8 0.73 0.21 M9 0.48 M10 0.94 0.99 0.08 The following list has statements about the classifiers. In the list, there is a single correct statement. Please identify the correct statement. Hint 1: recall that a classifier dominates another if both performance measures are better. Hint 2: to help you visualize and compare classifiers, you may want to plot the classifier data in a ROC graph (which will not be submitted). Select one: a. M9 dominates M7 ○ b. By swapping zeroes and ones, the performance of M1 does not change much ○ C. By swapping zeroes and ones, M4 can be improved d. M2 dominates both M3 and M6 ○ e. By swapping zeroes and ones, M1 can be improved
