In general it is enough to have a single layer of nonlinear neurons in a neural network in order to learn to approximate a nonlinear function. In such case general optimisation may be applied without too much difficulty. Example: an MLP neural network with a single hidden layer: Synaptic ...

Example: consider a network consisting of many neurons that are interconnected(互相連接 ) to form a web with no inputs or outputs. In such a system, the excited neurons will tend to excite other neurons, whereas the inhibited neurons will tend to inhibit others. In turn, the entire system...
