Which computational method (DCT, DWT, or EMD with PCs or ICs) provides the highest classification accuracy for automated diagnosis of arrhythmia beats from ECG signals?
The use of Independent Components on Discrete Wavelet Transform provides highly accurate automated classification of arrhythmia beats from ECG signals.
Desai et al. (2016) studied Arrhythmia. Independent Components (ICs) on Discrete Wavelet Transform (DWT) vs. Discrete Cosine Transform (DCT) and Empirical Mode Decomposition (EMD) methods was evaluated on Classification accuracy of five classes of arrhythmia beats. Automated diagnosis using Independent Components on Discrete Wavelet Transform and a k-NN classifier achieved 99.77% accuracy in classifying five types of arrhythmia beats.
