specifically, this is a similar example. this is actually the credit card application data we were looking at earlier. but just to demonstrate the problem when you don't scale your features. if we were trying to predict this yellow point on the left here you can see it far to the left and then a little bit above the red x. we're going to be looking at the features around us to try to find what point is closest to me that i can say that i'm going to be like that point. when we look at this with our human eyes we say obviously the red x underneath it
