Based on the equivalence between the objective function optimization and linear equations, the proposed scheme translates the optimization model into linear equations and then performs adaptive filtering by employing an effective iterative method for linear equations, namely Conjugate Gradient ( CG) algorithm. 该方案把最优化模型转化为线性方程组的形式,并用一种有效的迭代方法即共轭梯度(ConjugateGradient,CG)算法来实现自适应滤波。
Large numbers of experiments show that the combination strategy is effective, and the two algorithms have better performance and convergence than LU factorization and conjugate gradient method. 大量实验结果表明此结合策略是很有效的,得到的两种算法具有较快的速度和较好的收敛性。
While in the parameter optimization, we research some effective nonlinear optimization algorithms, such as conjugate gradient algorithm, gradient descent algorithm and quasi-Newton algorithm.

Recently, Hager-Zhang and Dai-Liao proposed some effective conjugate gradient methods. 近年来,Hager和Zhang及Dai和Liao提出了一些有效的共轭梯度法。
Quasi-Newton algorithm and conjugate gradient algorithm are both effective algorithms. In this paper, we mainly investigate the conjugate gradient algorithm. 拟牛顿法和共轭梯度法就是两类比较成功的方法,本文主要研究共轭梯度法。
