A hybrid optimization algorithm adapted to radial basis function (RBF) networks and an RBF nets-based state-dependent AR(X) model parameter estimation is presented. The proposed method (EA-SNPOM) merges an evolutionary algorithm (EA) with a gradient-based search strategy¡ªthe structured nonlinear parameter optimization method (SNPOM). It provides a global search with the EA and a local search via the SNPOM. The effectiveness of the resulting combination is demonstrated by several examples.

1. A hybrid optimization algorithm based on radial basis function (RBF) networks and an RBF nets-based state-dependent AR(X) model parameter estimation has been presented. 2. The proposed method (EA-SNPOM) combines the evolutionary algorithm (EA) and the structured nonlinear parameter optimization method (SNPOM, a gradient-based search strategy). 3. A global search with EA and a local search via SNPOM can be achieved. |
