The generalization performance of the learner is evaluated. In the measure, we should have the evaluation criterion to measure the generalization ability of the model. Performance metrics reflect task requirements, and using different performance metrics often leads to different judgments when comparing the capabilities of different models, which means that the model is relatively good or bad, and that the model is not only dependent on the algorithm and data, but also on the task requirements.

Test Set Note the trade-off between the amount of data that can be used for testing and training in the test set. Another consideration for selecting a test set is the similarity between the test set instance and the development set instance. The more similar the two datasets, the less confidence we have in extending the evaluation results to other datasets. Accuracy The simplest measurement used to evaluate a classification is accuracy. It is important to explain the accuracy score of a cl

parameters are the basis for commonly used evaluation methods. Through the values of these parameters we can calculate the ROC space and PR space of a point, multiple images can be more than one point, even the curve is called the ROC curve and PR curve.

The following table describes the evaluation metrics of several classifiers: Assume that a classifier is used in a training set composed of labeled tuples. P indicates the number of positive element groups, and N indicates the number of negative element groups. Measurement Formula
