1. Recall and precision Traditional Information Retrieval and evaluation indicators mainly include the recall and precision ratio, The query completion rate refers to the ratio of the number of relevant documents in the returned results to the total number of relevant documents in the system, which mainly reflects the integrity of the retrieval system recall resu

Abstract: filtering microblogging messages for Social TV, a bootstrapping approach to identifying relevant tweets for Social TV Social TV was named one of the ten most important emerging technologies in 2010 by the MIT Technology Review. Social televisionIs a general term for technology that supports communication and social interaction in either the context of watching television, or related to TV content. Some of these systems allow users to read microblogging messages related to the TV progra

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. Roc space (for real results gound Truth)Horizontal axis False Positive rate (FPR) = The proportion of the target in a non-target pixel (the smaller the better)Vertical axis True Positive rate (TPR) = The percentage that is correctly ch
