Details

The four regions of the sample space are,

  1. Points above the hyperplane and within the margin. Points closest to the margin boundary are returned.

  2. Points below the hyperplane and within the margin. Points closest to the margin boundary are returned.

  3. Points above the hyperplane. Points furthest from the hyperplane are returned.

  4. Points below the hyperplane. Points furthest from the hyperplane are returned.

If there are less than rho points remaining in any of these spaces only the remaining points will be returned.
