| Abstract: | Concentrating on the selection of the kernel function of relevance vector machine,this research has combined the locality- sensitive Gaussian kernel with the global sigmoid kernel,which has been used in the relevance vector machine modeling. It uses the differential evolution algorithm to optimize the parameters which are formed in the relevance vector machine with the combined kernel function. The optimized RVM with combined kernel function has been used in penicillin fermentation process modeling,and a much more accurate prediction than the single kernel function has been obtained. |
