When can we say an algorithm is parameter free?

1.1k Views Asked by At

I was reading the paper by Dr. Francesco at http://arxiv.org/abs/1406.3816. The author presented a kernel version of parameter-free algorithm. But, any kernel, AFAIK, takes some parameter(RBF bandwidth, polynomial degree etc. which needs to be properly tuned for better results). In this spirit, How can the algorithm in this paper be called "parameter-free"?
