函数变量

This method can reduce the number of input variable while the function is still unchanged. So the scale of Neural Networks can be reduced and the generalization can be enhanced.

这种方法在保证原有函数形式不变的前提下，简化了输入变量，缩小了神经网络的规模，增强了模型的泛化能力。

Kernel principal component analysis can compute principal components in high-dimensional feature space by means of integral operators and nonlinear kernel functions.It can effectively capture the nonlinear relationship in the process variables.

核主元分析方法通过集成算子与非线性核函数计算高维特性空间的主元成分，有效捕捉过程变量中的非线性关系。

Numerical Integration Single variable f - Calculates the definite integral of a single variable function f(x using numerical methods: The Trapezoidal, the Midpoint and the Simpson's method.

计算一个单精度变量的整数部分的函数f 使用的数学方法：梯形法、中间点中和辛普森方法。

The upper limit t and varable t in the integrand in Boltzmann hereditary integral are expressed as different forms, and explained as another meaning in this paper.

对以往遗传积分的表达式中积分上限t和被积函数中变量t给以不同的解释。

On the other hand,Raymond considered systemsgoverned by linear elliptic and parabolic differential equations with the integrand in costfunctional has to be concave in the state variable.

在那里，指标泛函中的被积函数关于状态变量必须是凹的。因而，那里所给的条件和Cesari条件是互不包含的。

The integrand in the variational principle is rewritten in symmetrical form for duality variables.

变分原理被积函数可导向对于对偶变量为对称的形式。

This function is pretty quick since it's operation does not perform any calculation but merely return the already known length of a string available in the zval structure (internal C struct used to store variables in PHP).

此函数执行起来相当快，因为它不做任何计算，只返回在zval 结构（C的内置数据结构，用于存储PHP变量）中存储的已知字符串长度。

Nown length of a string available in the zval structure (internal C struct used to store variables in PHP).

此函数执行起来相当快，因为它不做任何计算，只返回在zval 结构（C的内置数据结构，用于存储PHP变量）中存储的已知字符串长度。

The accumulate function sets an internal variable to the initial value.

accumulate函数将它的一个内部变量设置为指定的初值，然后在此初值上累加输入范围 accumulate

Given the maximum and minimum number of input variables and rules, a set of fuzzy models is constructed. Finally, the optimal fuzzy model is selected by the objective function, and is optimized by a genetic algorithm to achieve a good tradeoff between interpretability and precision.

最后给定最大最小的输入变量数目和规则数目，辨识得到一组模糊模型，利用模型选择目标函数，选择最优的模糊模型，并采用遗传算法进行优化，达到解释性与精确性的折衷。
