the impact representation you could reuse all those and engineered architectures and often they would you know counteract for the issues of handling long term dependencies in or an end with like an attention layer the like but they still require you know that engineering of each these tasks for each of these different architectures which means that you're still leaving performance on the head room you know it's not like where you're initializing the middle layer features of a CNN instead of like the edge detectors of the lower
