I am working on a problem to predict revenue generated by a film. I am using sklearn's support vector regression algorithm with polynomial kernel. I tried to find the degree which gives best accuracy using default value of regularization parameter. But, I got error percentage in the 7 digit range. So, I decided to increase variance, by tuning the regularization parameter.
So should I first assume a degree and find the regularization parameter which gives best result or vice versa?
Or is there something else that I should consider?
