Abstract

To solve the problem of SVR (support vector regression) model selection, this paper proposed a SVM (support vector machine) model parameter optimization algorithm based on gradient descent algorithm. The algorithm obtained the local optimal model parameter by minimizing the model evaluation criteria over the parameter set. Then on the basis of Riemannian geometry, a conformal transformation suitable for SVR was proposed which corrected kernel function in a data-based way. This algorithm can further enhance the generalization ability of SVR. The simulated results are illustrated to show the feasibility and effectiveness of the algorithm.
