Detailed Description

The Weighted Degree kernel of order d compares two sequences ${\bf x}$ and ${\bf x'}$ of length L by summing all contributions of k-mer matches of lengths $k\in\{1,\dots,d\}$ , weighted by coefficients $\beta_k$ . It is defined as

$k({\bf x},{\bf x'})=\sum_{k=1}^d\beta_k\sum_{l=1}^{L-k+1}I({\bf u}_{k,l}({\bf x})={\bf u}_{k,l}({\bf x'})).$

Here, ${\bf u}_{k,l}({\bf x})$ is the string of length k starting at position l of the sequence ${\bf x}$ and $I(\cdot)$ is the indicator function which evaluates to 1 when its argument is true and to 0 otherwise.
