Webexample. net = feedforwardnet (hiddenSizes,trainFcn) returns a feedforward neural network with a hidden layer size of hiddenSizes and training function, specified by trainFcn. Feedforward networks consist of a series of layers. The first layer has a connection from the network input. Each subsequent layer has a connection from the previous layer. WebJun 20, 2024 · 前馈网络. Feedforward Networks 也叫Multilayer Perceptrons(多层感知机),大致的结构如下图所示. 其中,每一个节点都可以看做是一个函数,将上一层传过来 …
