Compared with the classical bp algorithm , robust adaptive bp algorithm possesses some advantages as following : ( 1 ) increasing the accuracy of the network training by means of using both the relative and absolute residual to adjust the weight values ; ( 2 ) improve the robustness and the network convergence rate through combining with the robust statistic technique by way of judging the values of the samples " relative residual to establish the energy function so that can suppress the effect on network training because of the samples with high noise disturbances ; ( 3 ) prevent entrapping into the local minima area and obtain the global optimal result owing to setting the learning rate to be the function of the errors and the error gradients when network is trained . the learning rate of the weights update change with the error values of the network adaptively so that can easily get rid of the disadvantage of the classical bp algorithm that is liable to entrap into the local minima areas 與基本bp算法相比,本文提出的魯棒自適應(yīng)bp算法具有以下優(yōu)點(diǎn): ( 1 )與魯棒統(tǒng)計(jì)技術(shù)相結(jié)合,通過訓(xùn)練樣本相對(duì)偏差的大小,確定不同訓(xùn)練樣本對(duì)能量函數(shù)的貢獻(xiàn),來抑制含高噪聲干擾樣本對(duì)網(wǎng)絡(luò)訓(xùn)練的不良影響,從而增強(qiáng)訓(xùn)練的魯棒性,提高網(wǎng)絡(luò)訓(xùn)練的收斂速度; ( 2 )采用相對(duì)偏差和絕對(duì)偏差兩種偏差形式對(duì)權(quán)值進(jìn)行調(diào)整,提高了網(wǎng)絡(luò)的訓(xùn)練精度; ( 3 )在采用梯度下降算法對(duì)權(quán)值進(jìn)行調(diào)整的基礎(chǔ)上,通過將學(xué)習(xí)速率設(shè)為訓(xùn)練誤差及誤差梯度的特殊函數(shù),使學(xué)習(xí)速率依賴于網(wǎng)絡(luò)訓(xùn)練時(shí)誤差瞬時(shí)的變化而自適應(yīng)的改變,從而可以克服基本bp算法容易陷入局部極小區(qū)域的弊端,使訓(xùn)練過程能夠很快的“跳出”局部極小區(qū)域而達(dá)到全局最優(yōu)。
