or malignant. Now, think about the costsensitive classification, ie making an
error for one class is more costly than making an error in predicting the other.
Answer the following two subquestions:
Question pt In this case of cancer classification, which kind of
misclassification is more costly to patients? Note that cost here refers to not
just financial cost but cost to the patients in general.

order to reduce overall misclassification cost? Explain your answer in
sentences.
