比式判别法和根式判别法是对正项级数收敛性进行判别的两种广用的方法。

The ratio test and the root test are two widely used convergence tests for positive series.

而支持向量机(SVM)能够在一个高维特征空间中灵活的判别边界，具有很强全局收敛性。

The Support Vector Machine (SVM) can flexible to decide boundary in a high-dimensional feature space, because of its strong global convergence.
