Key result
Optimization methods improve ML and DL accuracy, sensitivity, and specificity for ECG classification.
Why the study?
It is difficult to detect cardiac status by naked eyes, and few studies show how optimization techniques aid feature selection and classification with machine learning and deep learning for ECG signals.
Optimization techniques combined with machine learning and deep learning can improve the accuracy, sensitivity, and specificity of automated ECG signal classification.
May enhance ECG classification in research; hypothesis-generating and should not yet change practice.
Electrocardiogram (ECG) is a visual representation of the heartbeat that can be used to detect cardiac problems. It helps in detection of normal or abnormal state of heart diseases. So, it’s difficult to detect the cardio logical status by naked eyes. So, features extraction from ECG signal is crucial to recognise heart disorders. After selecting significant features, classification can be done by machine learning (ML), and deep learning (DL). Most of the methods utilised to classify the electrocardiogram are based on 1-D electrocardiogram data. These methods focus on extracting the attributes wavelength and time of each waveform as an input but these algorithms behave different during selecting classification technique. Various ECG construal algorithms based on signal processing approaches have been planned in recent years. Few studies shows how optimisation techniques are helpful for feature selection and classification with ML and DL. This works compares the studies based on ML and DL. It also depicts how optimisation methods increases the accuracy, sensitivity and specificity of data.
