multikernel algorithm to provide a more localised estimation, a

direct benefit from larger training sets, and also to assign tailored

kernel combinations to each region of the input space.

9.6 Discussion

After revisiting the standard support vector regression framework,

we have reviewed three approaches to higher-dimensional kernels

(HDK): complex-, quaternion-, and vector-valued kernels. For each

of these cases, we have discussed their theoretical requirements

and have illuminated how their feature spaces allow for the design

of kernel estimation algorithms. We have also shown ...
