 \subsection{Polynomial Kernel}
 The polynomial kernel of degree $N$ is defined as $(1+<x,y>)^N$, where
-$<x,y>$ is the linear kenrel (usual scalar product). For weights we
-define the linear kernel to be $<x,y>=\frac{\sum w_xw_yxy}{\sum
-w_xw_y}$ and the polynomial kernel can be calculated as before
+$<x,y>$ is the linear kernel (usual scalar product). For the weighted
+case we define the linear kernel to be $<x,y>=\sum w_xw_yxy}$ and the
+polynomial kernel can be calculated as before
 $(1+<x,y>)^N$. Is this kernel a proper kernel (always being semi
 positive definite). Yes, because $<x,y>$ is obviously a proper kernel
