CWeightedDegreePositionStringKernel Class Reference


Detailed Description

The Weighted Degree Position String kernel (Weighted Degree kernel with shifts).

The WD-shift 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 $\beta_k$ allowing for a positional tolerance of up to shift s.

It is formally defined as

\begin{eqnarray*} &&\!\!\!\!\!\!\!k({\bf x}_i,{\bf x}_j)=\sum_{k=1}^d\beta_k\sum_{l=1}^{\!\!\!\!L-k+1\!\!\!\!}\gamma_l\sum_{\begin{array}{c}s=0\\ \!\!\!\!s+l\leq L\!\!\!\!\end{array}}^{S(l)} \delta_s\;\mu_{k,l,s,{{\bf x}_i},{{\bf x}_j}},\\ &&\!\!\!\!\!\!\!\!\!\! {\footnotesize \mu_{k,l,s,{{\bf x}_i},{{\bf x}_j}}\!\!\! =\!\! I({\bf u}_{k,l+s}({\bf x}_i)\! =\!{\bf u}_{k,l}({\bf x}_j))\! +\!I({\bf u}_{k,l}({\bf x}_i)\! =\!{\bf u}_{k,l+s}({\bf x}_j))},\nonumber \end{eqnarray*}

where $\beta_j$ are the weighting coefficients of the j-mers, $\gamma_l$ is a weighting over the position in the sequence, $\delta_s=1/(2(s+1))$ is the weight assigned to shifts (in either direction) of extent s, and S(l) determines the shift range at position l.
