Quiz on Pairwise Matching

Evaluate your learnings about binary classification and pairwise matching.

1

We evaluate the performance of a binary classification model on a test set of 1010 labeled examples. We observe tp=2tp=2 true positives, tn=5tn=5 true negatives, fn=4fn=4 false negatives, and fp=1fp=1 false positives. Which statement is correct?

A)

Precision equals tp/(tp+tn)=2/(2+5)tp/(tp+tn)=2/(2+5).

B)

Recall equals tn/(tn+fn)=5/(5+4)tn/(tn+fn)=5/(5+4).

C)

The F1F_1 score is the arithmetic average of precision and recall.

D)

Precision equals tp/(tp+fp)=2/(2+1)tp/(tp+fp)=2/(2+1).
