five nearest neighbors and you do this for each image so this image has these five nearest neighbors and so on so in step two what you're trying to do is you're going to try to pull together each image and its nearest neighbors in that in this this not in this space directly but you determine which ones are the nearest neighbor from this neural net where can you keep it constant that's how you determine what the nearest neighbors are in the first task and that is your NX set for X I and in the second step you're trying to make
