your data set X that's really another your data set X is this list basically of all the images in your data set and what we're going to do is you're going to take all of them using that neural network that you just trained and embed them into a latent space right here okay this is the latent space where you have done this self supervised training and now for each image right here so if this is X eye you're going to find its K nearest neighbors and they use I think they use five as a benchmark so you're going to find its nearest neighbors it's
