Suppose that a classifier computes a numerical score for an item… Suppose that a classifier computes a numerical score for an item based on its “confidence” that the item is a member of the target category. In using the classifier, you set a threshhold, accept the items whose score is higher than the thresshold, and reject items whose score is lower.For instance, suppose you have the following labelled data set, with the true labels (T if the item is actually in the category; F if it is not) and scores.NameabcdefghijLabelFTTTTFTTFTScore.95.92.85.84.81.75.71.69.62.56NameklmnopqrstLabelFFTFFTFFFFScore.51.48.43.42.43.25.21.15.08.01If you then set the threshhold at 0.50, the classifier will accept items a-k and reject items l-t. Compute precision, recall, and F-sore for threshholds 0.9, 0.7, 0.5, and 0.3. Computer Science Engineering & Technology Artificial Intelligence CSCI-GA 3812 Share (0)
