A novel method is proposed in this paper for the feature extraction of electrocardiogram (ECG). The shape characteristic of the QRS complex has been a diagnostic criterion of cardiac arrhythmia. In other words, geometric property of the QRS complex is a very important kind of feature. Different with other feature extraction algorithms, the proposed method utilizes geometric algebra (GA) to extract...
A novel method is proposed in this paper for the feature extraction of electrocardiogram (ECG). Different with other algorithms, the proposed method utilizes independent component analysis (ICA) and wavelet transform to get an ensemble feature composed of ICA-based features and the QRS complex width feature. The QRS complex is the most characteristic waveform of an ECG signal and its width has been...
A novel method for optimising the principal component analysis in feature extraction is proposed, which makes use of parallel coordinate plot for graphical presentation of multivariate information. The objectivity and automatization of above manual observation and filtering process is realized by algorithm. In supervised multivariate information classification, before feature extraction on principal...
Moxibustion has been one of the most important therapeutic methods in traditional Chinese medicine for thousands of years. It is meaningful to research on the mechanism of moxibustion and the techniques about how to realize the perfect efficacy with modern engineering technology. In this paper, the authors presented a series of research works on this, including: experiments on the indirect and direct...
