Classification

, Q1.)

One advantage of using the KNN classifier is that it is a transparent model, easy to use. Classification
quickly computed and no model assumptions made.



One disadvantage of using the KNN classifier is changing the k parameter / distance metric /
weighting function can have a big effect on the classification results.



Q2.)

Accuracy = (TP + TN) / (TP + TN + FP + FN)

Classifier 1 = (12+5) / (12+15+8+5)
=
=0.425

Classifier 2 = (17+16) / (17+4+3+16)
=
=0.825

a.) Classifier 2 more accurate.


b.) Sensitivity: TP / (TP + FN)
Specificity: TN / (TN + FP)
