逼近函数 meaning in English
approximate function
approximating function
approximation function
Examples
- Rational curves and rational surfaces , which are a class of important approximation functions , are extensive applied in cad / cam
有理曲线和曲面作为一类重要的逼近函数，在计算机辅助设计与制造中有着广泛的应用。 - This paper approximates non - linear function with wavelet neural network , whose ability of approximation function is discussed in theory
本文将小波神经网络用于逼近非线性函数，并从理论上讨论了它逼近函数的能力。 - By constructing approximate functions and using prior estimate and conversion of variable , it is proved that the inverse problem has weak solution for given initial value , boundary value and the oil output
通过变量和函数变换，作逼近函数和估计等方法，证明了对给定的初边值和石油产量，此反问题存在弱解。 - To choose wavelet function based on time - frequency region is put forward , time - frequency region composing of all of these wavelet functions can overlay wholly time - frequency region of non - linear function to approximate
本文提出了根据逼近函数的时频空间区域来选择小波基函数，使这些小波基函数共同构成的时频空间区域覆盖完逼近函数的时频空间区域。 - Because the choice of fuzzy set functions affects how well a fuzzy system approximates a function and gaussian bell - curve sets give richer fuzzy systems with simple learning laws , we choose gaussian function set as fuzzy set functions
因为隶属函数的选取会影响模糊系统逼近函数的效果，而高斯型隶属函数的钟形曲线只要简单的学习规则就可以表示丰富的模糊信息，我们选取高斯型隶属函数作为模糊集合函数。
