Manoeuvre a Cross-Spectral Algorithm and Machine Learning Approach to Categorize Seizures

Abstract

EEG signals are recordings of electrical activity in the brain, and they can be used to detect epileptic seizures. Cross-spectral analysis involves analyzing the spectral coherence between different frequency bands in EEG signals. Cross-spectral seizure detection is a technique used to detect seizures in electroencephalography (EEG) signals by analyzing the frequency content of the signal in different frequency bands. Spectral coherence is a measure of how correlated two signals are in the frequency domain, and it can be used to identify patterns in EEG signals that are characteristic of seizures. Even if the ECG, which provides a direct measure of heart rate, were polluted by noise or missing altogether, the heart rate computed from such signals would be erroneous. This necessitates the use of an accurate heart rate estimate, which is especially important when the ECG is noisy or missing. To put it another way, fusion combines cardiovascular data with no cardiovascular (NC) signals, which are not connected to cardiac activity but include signs of heartbeats. According to the results of our evaluation of standard datasets, they determined that the SSF-TKE approach is particularly successful at identifying R-peak artefacts in non-cardiovascular signals that ECG anomalies have contaminated. When tested on standard datasets, the beat SQI-based voting fusion technique demonstrated a high degree of accuracy in predicting heart rate from a fusion of multimodal information. Compared to the single signal technique, the fusion methodology out per-forms it when determining heart rate precision. This strategy was evaluated using ECG and ABP signals from a synthetic noise dataset, which was created by adding various forms of calibrated noise to clean signals and then testing the outcomes of the technique on those signals. As a result of our paper, we noticed that merging cardiovascular and no cardiovascular inputs increased the accuracy of physiological parameter assessment.
