查询词典 classification statistic

Based on the principle of PEC, surface cracks mainly affect the high frequency components and subsurface crack mainly affect the low frequency components, so the PEC signals can be analyzed in frequency domain, which can eliminate the influence of noises during measurement. A method of frequency spectrum separating point is proposed for flaw classification, which enhances the accuracy in classification of defects. The agreement between theory and experiment shows that the present method is valid and applicable.

通过对脉冲涡流的理论分析发现，表面裂纹主要影响脉冲频谱中的高频成分，而表面下裂纹主要影响脉冲频谱中的低频成分，因此可以将时域中易受噪声影响的脉冲涡流信号变换到频域分析，提出了"频谱分离点"的方法来对裂纹进行分类识别，提高了缺陷分类识别的正确率，理论分析和实验结果相一致，证明了该方法的正确性和有效性。

The support vector machine is one new general learning method,which proposed in the statistical Learning Theory,mainly applied in the data classification and regression estimate,meanwhile the main basis in plant classification is plant's outward characteristic.

支持向量机是在统计学习理论基础上提出的一种新型的通用学习方法，主要应用于数据的分类和回归估计，而植物分类的主要依据是植物的外观特征。

To denoise, the Byes principle can be applied to train the mass sample, and promote the representability of the characteristic vector. The practice proved that the BP neural networks have capacity of error acceptance, and can classify the vehicle samples not trained. The Fast Vehicle Classification system can meet the demand of the high precision classification.

对于测量系统提取中的一定范围中的数据"噪声"，以Bayes法则进行对大量样本先验去除"噪声"，提高了特征向量的代表性，理论与实际证明这样得到的BP网络有强容错能力，识别没有看到过的汽车样本能够达到高精度识别要求。
