 This project aims at using machine learning approaches to suppress BCG artifacts. We will use Unet as the artificual neural network structure to tackle this challenge.

 ## Data
 
 Data were EEG time series collected inside a 3T MRI scanner (Skyra, Siemens). EEG were sampled by a 32-channel systemm (Brain Products) with electrodes arranged by the international 10-20 standard. EEG were sampled at 5,000 Hz.
