r - Meaning of Epsilon in SVM regression - Cross Validated

WebThe difference between ϵ -SVR and ν -SVR is how the training problem is parametrized. Both use a type of hinge loss in the cost function. The ν parameter in ν -SVM can be used to control the amount of support vectors in the resulting model. Given appropriate parameters, the exact same problem is solved. 1.

WebJan 31, 2024 · Traditional ϵ -SVR works with the epsilon-insensitive hinge loss. 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.
