Preprocessing of eeg signals
Webeeglib. The module eeglib is a library for Python that provides tools to analyse electroencephalography (EEG) signals. This library is mainly a feature extraction tool that includes lots of frequently used algorithms in EEG processing with using a sliding window approach. eeglib provides a friendly interface that allows data scientists who work ... WebHowever, EEG is usually buried under various noises and often requires preprocessing to obtain clean data for analysis. The purpose of this study is to propose a deep learning model suitable for estimating cognitive workload from raw EEG signals without using any preprocessing techniques. Specifically, the dataset consisted of EEG from two
