Dimension reduction and classification in ECG signal interpretation using FA & PCA: A comparison
VARUN GUPTA,MONIKA MITTAL 장전수학회 2018 Proceedings of the Jangjeon mathematical society Vol.21 No.4
Electrocardiogram (ECG) is the electrical activity of the heart. It consists of P-wave, QRS complex and T-wave. Each beat shows electrical impulse propagation in the heart of the body. Due to higher dimension of ECG signal, its analysis needs dimension reduction tech- niques for pre-processing of the data. In this paper, authors proposed Factor Analysis (FA) and Principal Component Analysis (PCA) for re- ducing dimension of the ECG signal. The choice of its usage depends on problem which is clearly known and specied. Physionet ECG data- base (MIT-BIH long term ECG database, Ventricular Tachyarrhythmia, AHA(American Heart Association) Database) and real time ECG data- base has been used in this paper for checking detector performance using FA and PCA. PCA gave better results than FA. SNR (Signal to Noise Ratio) is also checked and calculated that is 93.25 dB and 91.25 dB for PCA and FA respectively. Dierent work proposed by dierent authors on ECG signal classification has been compared.
