Splettrainbr is a network training function that updates the weight and bias values according to Levenberg-Marquardt optimization. It minimizes a combination of squared errors and weights, and then determines the correct combination so as to produce a network that generalizes well. The process is called Bayesian regularization. SplettrainFcn的属性值一旦发生变化，网络训练参数（net.trainParam）将被设置为新的训练函数所包含的参数及其默认参数值。 mathwork官方在 mathworks.com/help/deep 给出了不同方法的对比。 参数属性 1.adaptParam属性 net.adaptParam属性定义为当前网络权值/阈值调整函数的参数及参数值，取决于当前的权值/阈值调整函数（net.adaptFcn），可以查看有 …
