  1. Using the regularized greens functions and a duality argument, it is proved that the mixed finite element method proposed in this paper possesses the superconvergence by almost one order maximum norm estimates for the l2 projection of the function and quasi - optimal maximum norm estimates for the associated vector function for a strongly nonlinear second order elliptic problem

    本文利用正規格林函數及對偶論證技術證明了一類強非線性二階橢圓問題混合元方法對函數的l2投影具有幾乎超收斂一階的最大模誤差估計，對伴隨向量函數具有擬最優最大模誤差估計
  2. In case of high input dimension system model, taking norm of input vector as the input of wavelet network instead of using tensor product method to construct wavelet network, which could solve the problems of high computation and curse of dimensionality. in the selecting of specific wavelet basis, this thesis first gets initial wavelet basis collection according to spectrum analysis, then gives the least squares regression algorithm to optimize wavelet basis collection based on the least estimation error criteria, which could also initialize the model parameters and increase the speed of convergence

    對于具體的模型小波基函數選擇，本文首先對樣本數據進行時頻域分析，根據小波基函數時頻空間覆蓋樣本時頻空間的原則，在小波框架中選擇建模所用的函數集，然後根據估計誤差最小準則，給出最小二乘回歸優選演算法以進一步優化小波基函數集。
