given these two patches to a neural network the neural network should say hey this patches to the right of this reference patch so look at look at its best looked at from this figure so you take an image you take an approximately three by three grid of non-overlapping patches and now given the blue patch you're trying to predict that the yellow patches to the top right corner so you can number the surrounding patches from one to three so on until eight so and you basically have eight categories for a classification
