基本的NN概念
1.Is a control method basically not depends on the Mathematical Model of operational objectives & environment
2.Is suitable for the controlled objectives with uncertainty, complex, inaccuracy or high non-linearity
3.Has strong Adapting, Study functions, Fault tolerance, potential distributed concurrent computing and can treat multi transferred information
特点
structure ,function, link-weight coefficient,learning method
其实可以理解成一个输入输出模型，中间有带权重值的传递函数。
最神奇的，NN具有强大的容错功能，假如输入的花有一个元素有问题，并不影响输出结果的正确性，神经网络仍可以判断出输入是花。
