Description: 提出了一个新的超声缺陷自动识别系统。该系统采用小波包分解提取超声信号的特征,采用混沌遗传算法来消除冗余和不相关的特征,并采用支持向量机(SVM) 来对缺陷进行识别。-Proposed a new ultrasonic flaw Automatic Identification System. The system uses wavelet packet decomposition extract the characteristics of ultrasonic signals using chaos genetic algorithm to eliminate redundant and irrelevant features, and using support vector machine (SVM) to identify defects.

Description: The authors present an automatic classification of different power quality (PQ) disturbances using
wavelet packet transform (WPT) and fuzzy k-nearest neighbour (FkNN) based classifier. The training data
samples are generated using parametric models of the PQ disturbances. The features are extracted using
some of the statistical measures on the WPT coefficients of the disturbance signal when decomposed upto
the fourth level. These features are given to the fuzzy k-NN for effective classification. Platform: |
