title: K Nearest Neighbor classifier
body: <p>I have set of about 200 points (x,y) of an image. The 200 data belong to 11 classes (which I think will become the class labels). My problem is how do I represent the x, y values as one data?</p>
  
  <p>My first thought is that I should represent them separately with the labels and then when I get a point to classify, I will classify x and y separately. Something in me tells me that this is incorrect. </p>
  
  <p>Please advice me how to present the x,y value as one data element.</p>
