Expenses estimated for the equipment based on the optimal parameters ε -SVR

Support vector regression machine (SVR) can establish the expenses estimate model according to the principle of the structure minimum risk. It reaches better accuracy in the small sample estimated, but there are not a set of integrity theories for choosing the parameters of SVR. This paper adopts the methods of varied step to search the optimal parameters. It use the combination accuracy to evaluate the estimated effect, research the influence of the parameters combined form to the estimated accuracy. Then we can assurance the optimized combined form of the parameters. The example indicates the optimized combined form of the parameters can improved the expenses estimated accuracy.
