this ResNet 50 right here if it wants to if you simply want to make the two representations close what's the best thing it can do you can simply map all the hidden it can simply have the constant function H equals 0 or something like this just a constant function because then this loss here is always going to be 0 like perfect okay so no matter what image comes in if you always map it to the same thing you will always be close in representation space and therefore you always win that doesn't learn a really good
