classifier those are two different samples so you can do many of those things and they have to kind of augmentations they have what they call weakly augmented and strongly augmented right so in the weakly augmented pipeline I think they just they crop and they they shift and they rotate or something like this so you can see here this this horsey here it is something like it's cropped here about then it is turned slightly to the left and then yeah I think that's it so they crop they rotate and then they also flip
