subsequently we will find out how taking a self supervised approach to deep learning can help us overcome or at least mitigate that core weakness and finally we will look into an industry case that hopefully gives you a good idea of how you can use self supervision in practice to make your models better and more robust but first let's look into supervised learning probably some of you or maybe if many of you know this data set it's an incredibly popular famous data set even containing images of obviously cats and dogs and this data
