representation so if you only reconstruct from here you ignore the rest you get you get sort of high frequency information if you only reconstruct from here ignore this you just run through this network you can reconstruct a low-resolution version so this is you can think of this as like nonlinear wavelets if you want write the system so naturally learns to represent this let me skip this ok talk about this really quickly so something that's become very popular in the in the business is something called version of tiny coders
