descent method

基本解釋

The algorithm of studying bases on the foundation of the descent method most rapidly, and was improved.
學(xué)習(xí)算法在最速下降法的基礎(chǔ)上給出，并加以改進。
Since it adopt the steepest descent method in nonlinear programming, it has the drawback that easy converge to a local minimum point of the error function.
由于它采用非線性規(guī)劃中的最速下降法，因而存在極易陷入局部極小的缺陷。
And the three optimization problems are solved respectively by the conjugate gradient method, the adaptive bivariate shrinking and the gradient descent method.
并提出分別采用共軛梯度法、二元自適應(yīng)收縮法以及梯度下降法對以上優(yōu)化問題求解。
