The value of ϵ defines a margin of tolerance where no penalty is given to errors. Remember the support vectors are the instances across the margin, i.e. the samples being penalized, which slack variables are non-zero. The larger ϵ is, the larger errors you admit in your solution. the prince of egypt dreamworks
