of the distribution a lot more muscles tissues and brittleness we're seeing and again this is still some of the best stuff we've got it's combining supervised learning and unsupervised learning but there's hints as we're going to go through here that these self supervised methods and unsupervised pre training is really helping with the robustness we're still not there yet but we're making progress and all that's being driven by moving away from a purely supervised learning framework to moving to these like hybrid Android training and pre
