Polynomial kernel in SVM in e1071 package
Dear list,
In some places (for example,
http://en.wikipedia.org/wiki/Support_vector_machine) , the polynomail
kernel in SVM is written as (u'*v + 1)^d, while in the document of
svm() in e1071 package, the polynomial kernel is written as
(gamma*u'*v + coef0)^d. I am a little confused here:
When doing parameter optimization (grid search or so) for polynomial
kernel, does it need...
