power ratio
Examples
- 4 different types ’ features were generated , namely ar model parameters , power spectral frequency band intensity , energy for wavelet packet decomposition , wavelet packet entropy . every type of features were extracted respectively using pca and ica method and classified using linear neural network , knn and bp network
建立了ar模型参数、功率谱估计频带强度、小波包分解能量比率、小波包熵四种特征,分别使用pca与ica进行特征提取,采用线性神经网络、 k -紧邻法、 bp神经网络四种分类器进行分类。
