To reduce the iterative time and speed constringency in conventional BP algorithm,a improved weighted algorithm,which combines the method of negative gradient descent with DFP variable scale algorithm,is presented in the paper.

In view of the problem that the nearest neighbor-clustering algorithm can not reflect the distribution of study samples,an improved learning algorithm is proposed that the center,width and weight are adjusted on-line using negative gradient descent.

Combined algorithms for training RBF neural networks based on genetic algorithms and gradient descent;

Thorax multimodal medical image registration based on adaptive free-form deformation and gradient descent

A practical cooling regime was established then, and a network with better performances was obtained by combining simulated annealing algorithm with gradient descent method.

On the basis of data mining,a new method is developed for identifying fuzzy model,updating its parameters and determining optimal division of output space simultaneously by means of fuzzy sets theory and the improved gradient descent method.

Levenberg Marquardt (LM) algorithm is a combination of neural network, Gauss Newton method and gradient descent method, so it has the abilities of self learning, fast convergence and global search.

Two ways are used to design the network,the one is the direct energy descent method,and the other is the gradient descent method.

Comparison between GA and gradient descent algorithm in parameter optimization of UPFC fuzzy damping controller;

A few or all of the parameters of the controller are adjusted by using the gradient descent algorithm to minimize the output error.

A robust speech recognition system based on discriminative learning of environmental features is proposed for recognition of environmental features in high noise background, and a gradient descent algorithm was adopted for parameters optimization.
