why we extract feature of eeg signal for network neural? (energy, energy power density, convariance, entropy)?

I read more thesis for analysis eeg, but i dont understand why must extract feature, every one can explain detail (energy, energy power density, convariance, entropy). Please!

what do i find documents for this thesis? you can share documents?

thank everyone! --------------------------------------------- you can send to my mail: [e-mail]

[Greg Heath]

Feature extraction allows models to concentrate on the characteristics of the input data that are the most correlated with the desired output. Too much input data that has no output predicting qualities acts as noise and foils the ability to obtain good results

Hope this helps.
