Web12. I am trying to fit a SVM to my data. My dataset contains 3 classes and I am performing 10 fold cross validation (in LibSVM): ./svm-train -g 0.5 -c 10 -e 0.1 -v 10 training_data. The help thereby states: -c cost : set the parameter C of C-SVC, epsilon-SVR, and nu-SVR (default 1) For me, providing higher cost (C) values gives me higher accuracy. Web1 Answer. Sorted by: 8. Yes. This can be related to the "regular" regularization tradeoff in the following way. SVMs are usually formulated like. min w r e g u l a r i z a t i o n ( w) + C l o s s ( w; X, y), whereas ridge regression / LASSO / etc are formulated like: min w l o s s ( w; X, y) + λ r e g u l a r i z a t i o n ( w).

Web20 de mai. de 2013 · You just happen to have a problem for which the default values for C and gamma work well (1 and 1/num_features, respectively). gamma=5 is significantly larger than the default value. It is perfectly plausible for gamma=5 to induce very poor results, when the default value is close to optimal. WebIntuitively, the gamma parameter defines how far the influence of a single training example reaches, with low values meaning ‘far’ and high values meaning ‘close’. The gamma … how to look up taxonomy code for npi
