Linear combination methods are the most popular and have two basic categories: unweighted sum (i.e., using sum or mean of the kernels as the combined kernel) and weighted sum. In the weighted sum case, we can linearly parameterize the combination function: P. kh(xi xj) = fh(fkm(xm xm. i j )gP m=1jh) =. åhmkm(xm xm. PIMKL is a methodology for phenotype prediction from multi-omic measurements, e.g., mRNA, CNA, etc, based on the optimization of a mixture of pathway-induced kernels. Such kernels are generated by .

Multiple Kernel Learning (MKL) methods overshadow this issue, by learning a consensus kernel K from a set of predefined candidate kernels {K G (i)} i = 1 k, where k is the number of given kernels. The sought kernel K is regularized towards the predefined candidate kernels via a penalty function h K , { K G ( i ) } i = 1 k , w which is added as . Abstract.
