To the problem that large-scale labeled samples isn't easy to acquire in the course of SVM training, the active learning strategy is used in the SVM training and an incremental training algorithm of active SVM based on the uncertainty based sampling of distance ratio is proposed in the paper. The experimental results show that the active SVM learning strategy can considerably reduce the labeled samples and costs compared to the passive learning method, and at the same time it can ensure the accurate classification performance is kept as the passive SVM and also expedite the SVM training.

针对 SVM训练学习过程中难以获得大量带有类标注样本的问题，本文将主动学习策略应用于SVM增量训练中，提出了一种基于距离比值不确定性抽样的主动SVM增量训练算法，实验结果表明在保证不影响分类精度的情况下，应用主动学习策略的SVM选择的标记样本数量大大低于随机选择的标记样本数量，大大降低了标记的工作量或代价，而且训练速度同样有所提高。
