是本科毕设的题目，数据模型归一化，模态振动，可以实现模式识别领域的数据的分类及回归，针对EMD方法的不足,进行逐步线性回归，结合PCA的尺度不变特征变换(SIFT)算法。- The title of the commercial is undergraduate course you Normalized data model, modal vibration, You can achieve data classification and regression pattern recognition, For lack of EMD, Stepwise linear regression, Combined with PCA scale invariant feature transform (SIFT) algorithm.
