The Basics of Classifier Evaluation: Part 1 What’s Wrong with Accuracy?Other Evaluation MetricsExpected CostLingering QuestionsTo illustrate the problems, let’s start with a simple two-class domain. Every classifier for this domain sees examples from the two classes and outputs one of two possible judgments: Y or N. Given a test set and a specific classifier, you can place each decision as: 1. a positive example classified as positive. This is a true positive. 2. a positive example misclassified as negative. This is a false negative. 3. a negative example classified as negative. This is a true negative. 4. a negative example misclassi…
