摘要：
Wavelet Support Vector Machines (WSVM) using the Mexican Hat wavelet kernel has been used to nonlinear system identification successfully, but its universal approximation property has never been proved in theory. Based on Stone-Weierstrass Theorem, the universal approximation property of the WSVM to arbitrary functions on a compact set is proved with arbitrary accuracy. These simulations show the WSVM is very effective in nonlinear system identification, and can deduce noise of the system, so WSVM has great potential applications in the function estimation, nonlinear system identification, signal processing and control.
