函数的逼近 meaning in English
approximation of function
Examples
- The fuzzy hyperbolic model , a new approach for modeling of nonlinear system , is subsequently discussed for its validity . based on selecting the initial weights of neural network according to the priority of each input , the parameters can be identified by using bp neural network , which is good for reducing the randomness of initial weights and computing time . by combining self - study ability of neural network with knowledge - expression of fuzzy set theory , fuzzy neural network with self - correction of membership function is lastly constructed to make the approximation of some nonlinear functions
同其它神经网络模型相比此模型权系数的初始值可以根据各个输入变量在模型辩识中的重要性进行选择，减少了初始权值设定的随机性，从而缩短了模型辩识时间最后利用神经网络所具有的自学习能力结合模糊控制较强的知识表达能力，构造具有自动调整模糊隶属度函数的模糊神经网络，并利用它实现非线性函数的逼近。
