gradient descent method

基本解釋

Two ways are used to design the network, the one is the direct energy descent method, and the other is the gradient descent method.
有兩種方法可以用來(lái)設(shè)計(jì)網(wǎng)絡(luò)，一是能量下降法，另一個(gè)是梯度下降法。
The essence of back propagation networks is that make the change of weights become little by gradient descent method and finally attain the minimal error.
其實(shí)質(zhì)是采用梯度下降法使權(quán)值的改變總是朝著誤差變小的方向改進(jìn)，最終達(dá)到最小誤差。
Instead of gradient descent method, recursive least-square algorithm is used to train the fuzzy neural network to overcome the defect of the low convergence rate and local minimal.
為了克服傳統(tǒng)的梯度下降法收斂速度慢、容易陷入局部極小值的缺點(diǎn)，該方案采用遞推最小二乘法訓(xùn)練模糊神經(jīng)網(wǎng)絡(luò)。
