For problems in which Levenberg-Marquardt does not produce as accurate results as desired, or for large data problems, consider setting the network training function to Bayesian Regularization ( trainbr ) or Scaled Conjugate Gradient ( trainscg ), respectively, with either SpletTrain the network net using the training data. net = train (net,x,t); View the trained network. view (net) You can see that the sizes of the input and output are 1. Estimate the targets using the trained network. y = net (x); Assess the performance of the trained network. The default performance function is mean squared error.

This is the default training algorithm and the same as clicking Train. Training with Levenberg-Marquardt ( trainlm) is recommended for most problems. For noisy or small problems, Bayesian Regularization ( trainbr) can obtain a better solution, at the cost of taking longer. night at the museum jedediahSplettrainlm is a network training function that updates weight and bias values according to Levenberg-Marquardt optimization. trainlm is often the fastest backpropagation algorithm in the toolbox, and is highly recommended as a first-choice supervised algorithm, although it does require more memory than other algorithms. nppoa facebookSplet% net.trainFcn = 'trainoss'; % OneStep Secant Algorithm,计算量和内存需求均比BFGS算法小,比共轭梯度算法略大 % (中型网络的首选算法) %net.trainFcn = 'trainlm'; %Levenberg-Marquardt算法,内存需求最大,收敛速度最快 % net.trainFcn = 'trainbr'; % 贝叶斯正则化算法 nppn141bfcn-rcSplet03. dec. 2024 · Teams.
