In this project, EEG signals recorded from healthy subjects, seizure free epileptic subjects and seizure epileptic subjects were represented as image by using short time Fourier, wavelet and Hilbert-Huang transforms. Then, CNNs are trained with these images. Finally, unseen images classified with trained networks. With different configurations an accuracy of 100% is achived.
EEG Classification Using Signal Transformation and CNN
In this project size, shape and location information were read by sensor. Due to noise, sensor data could not be used directly. Therefore, three different CNNs trained for predicting these values. Finally, a GUI was created for testing purpose.
Real-Time Object Size, Shape and Location Prediction
Event related potential (ERP) analysis of continuous EEG signal. Epoching, filtering and noise rejection of continuous EEG signals. Creating line and topographic graphs of EEG bands for stimuli locked events.
