representations of the data points and in this case for this spiral dataset what happens is so in red you see again the red classes in blue the blue class it's 2d so you can plot it what it does is it bunches up the hidden representations fairly fairly so it bunches them kind of up it spreads them out in directions here here here most are bunched up here and it does these kind of weird arrangements here with the pockets of those and of course the neural network is powerful enough such that it can actually you know separate
