    针对SVM法线特征筛选算法仅考虑法线对特征筛选的贡献,而忽略了特征分布对特征筛选的贡献的不足,在对SVM法线算法进行分析的基础上,基于特征在正、负例中出现概率的不同提出了加权SVM法线算法,该算法考虑到了法线和特征的分布.通过试验可以看出,在使用较小的特征空间时,与SVM法线算法和信息增益算法相比,加权SVM法线算法具有更好的特征筛选性能.(Normal feature selection for SVM algorithm only considered normal for the contribution of feature selection, to the neglect of the characteristics of the distribution of feature selection have contributed to the lack of normal SVM algorithm based on the analysis, based on the characteristics of the positive and negative cases emergence of a different probability-weighted normal SVM algorithm, which takes into account the distribution and characteristics of normal. through the test can be seen in the use of smaller feature space, the normal and the SVM algorithm and information gain algorithm, normal weighted SVM algorithm has better performance of feature selection.)

    优点:1.对于信噪比高的信号滤波效果好; % 2.对于边沿的保护强过阈值滤波,不会产生阈值滤波情况下的过于平滑与Gibbs现象。 %缺点:1.由于对边沿信号没做任何处理,所以边沿可能会有脉冲噪声保留下来; % 2.计算相关系数中,如果计算出来的小波系数点位置偏差大,则相关系数计算受影响; % 3.需要迭代运算,迭代的噪声能量阈值选取很重要,这里以开始段无信号处估计噪声; % 4.需要迭代运算,所以运算量比阈值法大; % 5.受分解层次影响,在大尺度上小波系数点位置偏差更大,相关系数计算不准确。 %需要具体调整的地方:1.分解的尺度;()
