augmentations are very powerful and the way you design them basically if you one of these augmentations is a random crop which means if you have an image you randomly crop out like part of that image and then that's your training sample and not the entire thing so by doing this you basically teaching the model to ignore the exact location and scale of things on an image and you can do this because you as a human know that you know i can zoom in i can zoom out into something and it won't change what's on the picture and so
