双语例句
- Incorporating the sample distribution information into the process of feature extraction is beneficial to promote the classification performance of features.
把样本分布信息融于特征提取过程将有助于提高特征的分类能力。 - We use the information provided by sample projection distribution and sample size to determine the ratio of two classes of penalty factors and then obtain a new separating hyperplane.
