Practice Exercises 3 Classifier C 1 which always predicts negative (a rather useless clas- sifier of course). Classifier C 2 which predicts positive in 80% of the cases where the person actually has the disease, but also predicts positive in 5% of the cases where the person does not have the disease. Classifier C 3 which predicts positive in 95% of the cases where the person actually has the disease, but also predicts positive in 20% of the cases where the person does not have the disease. Given the above classifiers, answer the following questions. a. For each of the above classifiers, compute the accuracy, precision, recall and specificity. b. If you intend to use the results of classification to perform further screening for the disease, how would you choose between the classifiers. c. On the other hand, if you intend to use the result of classification to start medication, where the medication could have harmful effects if given to someone who does not have the disease, how would you choose between the classifiers? Answer: No Answer

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
