Multi-layer adaptive parameters optimization approach for support vector machines

A novel least squares support vector machines (LS-SVM) for function estimationis is presented. And then, a hyper parameters and kernel parameters optimization approach called multi-layer adaptive best-fitting parameters search method is developed. According to different learning problem, the optimization approach can obtain appropriate LS-SVM parameters adaptively. Non-linear control system identification is studied using the improved LS-SVM. The results show that the optimization approach can induct best-optimized parameters for LS-SVM, and optimized LS-SVM provides excellent control system identification precision.
