Extract features from brainwave signals




I am using the muse monitor app for recording the muse data. It records 256 samples in 1s and gives reading for all five power bands for each of the 4 electrodes. I taking a frame size of 5s. Can someone suggest some technique to extract features from the brainwaves signals for one window.


What’s a “feature” ? What’s a One Window?


Actually I am splitting my recording using 5 sec window (sliding window). So now I have (n,256,no. of brain waves columns). What are some feature extraction techniques I can use
