from every point, so that the dataset will be centered at the origin. This doesn’t change the structure of our data at all, but eases calculations. 1. Variance In the dual space, the vector x’s components are the x-coordinates of each example, i.e. Vx=(x1, x2, x3). Likewise, Vy=(y1,y2,y3). Remember
