When applying these predictors in practical studies, their predictive performances should be well understood. Different performance measures are applied in various studies as well as different evaluation methods. Even for the same performance measure, different terms, nomenclatures or notations may appear in different context. Results: We carried out a review on the most commonly used performance measures and the evaluation methods for bioinformatics predictors. Conclusions: It is important in bioinformatics to correctly understand and interpret the performance, as it is the key to rigorously compare performances of different predictors and to choose the right predictor.展开更多

At present, the separate school running system from many local junior and senior high schools makes it difficult for senior high school English teachers to exchange teaching communication. This paper probes into the factors that influence the connection between junior high school English teaching and senior high school English teaching, and explores how to deal with the connection in English teaching between junior and senior high schools from four aspects, such as, psychological guidance, teaching strategies, learning strategies and evaluation methods.展开更多

文摘Smooth degree of connection on English teaching in Junior and Senior high schools directly affects the quality of English Teaching in senior high school. At present, the separate school running system from many local junior and senior high schools makes it difficult for senior high school English teachers to exchange teaching communication. This paper probes into the factors that influence the connection between junior high school English teaching and senior high school English teaching, and explores how to deal with the connection in English teaching between junior and senior high schools from four aspects, such as, psychological guidance, teaching strategies, learning strategies and evaluation methods.
