R e1071 svm what is eps

WebDescription. svm is used to train a support vector machine. It can be used to carry out general regression and classification (of nu and epsilon-type), as well as density-estimation. A formula interface is provided. 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.
