WebApr 10, 2024 · While STFT reveals the frequency information, CWT preserves information in the time-frequency domain of EEG signals at a particular point in time. A CNN with Stacked AutoEncoder (SAE) model resulted in an accuracy of 75.1% which was 2.7% more accurate than using CNN alone . This model used STFT to convert EEG time series into 2D images. WebMay 1, 2024 · For the transient responses which are not specifically time-locked, the time-frequency (TF) images of EEG signals have become one of the more popular techniques of today’s research. The TF images are often used for extracting the features to feed a neural network classifier, and most TF methods are based on the short-time Fourier transform ... sprint s02
