2. Divide into 2s epochs
Do below for each epoch
-Brainwaves (delta, theta, alpha, beta, gamma)
→ channel coherence
→channel correlation Pearson
Embedding a lower dimensional manifold
-reduce dimensionality
→reduce component analysis
→Localized linear embedding (tSNE)
-Look at distances in reduced space between 2013 & 2014 baselines

### PreProccessing
* Seperate out Different waves
* Features extraction using neural network
* FFT : static
* Short-Time FFT : FFT with window
* Wavelet

### Prediction Model
## Results
The data did not show siginificant differences in the channel cohernece in alpha frequency between concussed and non concussed subjects. Additional features need
to be analyzed in order to determine if EEG is a reliable identifier for a subject with mTBI.
