replace the convolutions with attention modules or replace them entirely so the entire model is going to be just an attention model so no more convolutions in it and they perform pretty well in classic tasks like they they test on imagenet classification they perform pretty well and they achieve state-of-the-art on some of these segmentation tasks so we'll go through the model right here this is a very very extensive paper in terms of experimental evaluation what i want to get into is mainly how the method works
