Precision-Recall question in Homework 1

In the Precision-Recall question of homework 1, the expected answer is this:



In the slides, the precision recall curve was plotted at specific recall values (0, 0.1, 0.2, etc.). Some of you misinterpreted that to mean “You should plot the precision-recall curve at only those points at which a relevant document is retrieved.” That is not true in general.


Thanks and Regards,
