What is the advantage of that ?
Uh
Well , it 's that by the for the moment we have , uh , something that 's discriminant and nonlinear. And the other is linear but it 's not discriminant at all. Well , it 's it 's a linear transformation , that  Uh
So at least just to understand maybe what the difference was between how much you were getting from just putting the frames together and how much you 're getting from the discriminative , what the nonlinearity does for you or doesn't do for you. Just to understand it a little better I guess.
