样本构成 meaning in English
structure of sample
Examples
- Thus the scale of the training data set is reduced greatly and the training speed of svm is improved enormously . because the decision boundary of svm is only determined by support vectors , the classification accuracy is almost preserved when other samples are omitted
在svm学习之前，首先剔除训练样本集中距离判决边界远的样本，选取靠近判决边界的样本构成有效训练样本集，然后用svm对有效样本集进行学习，这样大大降低了训练样本集的规模，提高了svm的学习速度。
