Energy function

英语例句库

While blending factors are gained using the energy function that contains image gradient,which conquers the blur and mackle problems in the overlap area if using the tradition linear weight function.

最后对于传统图像融合处理中采用线性加权函数通常引起的最终拼合图像重叠区域模糊问题,构造了包含图像梯度的能量函数,用于计算重叠区域的全局最优融合因子。

原声例句
中高级英语短文

Because it requires so much energy to function, our brain is lazy—it often tries to go for the processing approach that requires the lowest cognitive load possible.

因为它需要如此多的能量来运作，我们的大脑是懒惰的——它经常试图选择需要尽可能低的认知负荷的处理方法。

最优化 Mathematical optimization

（重定向自Energy function）

最优化，是应用数学的一个分支，主要研究以下形式的问题：

主要研究以下形式的问题：

这类定式有时还称为“数学规划”（譬如，线性规划）。许多现实和理论问题都可以建模成这样的一般性框架。

典型的，A一般为欧几里得空间\mathbb{R}^n中的子集，通常由一个A必须满足的约束等式或者不等式来规定。 A的元素被称为是可行解。函数f被称为目标函数，或者代价函数。一个最小化（或者最大化）目标函数的可行解被称为最优解。

一般情况下，会存在若干个局部的极小值或者极大值。局部极小值x^*定义为对于一些\delta>0，以及所有的x 满足

Mathematical optimization 最优化

（重定向自Energy function）
Graph of a paraboloid given by f(x, y) = −(x² + y²) + 4. The global maximum at (0, 0, 4) is indicated by a blue dot.
The graph of a strictly concave quadratic function is shown in blue, with its unique maximum shown as a red dot. Below the graph appears the contours of the function: The level sets are nested ellipses.

In mathematics, computer science and operations research, mathematical optimization (alternatively, optimization or mathematical programming) is the selection of a best element (with regard to some criteria) from some set of available alternatives.

In the simplest case, an optimization problem consists of maximizing or minimizing a real function by systematically choosing input values from within an allowed set and computing the value of the function. The generalization of optimization theory and techniques to other formulations comprises a large area of applied mathematics. More generally, optimization includes finding "best available" values of some objective function given a defined domain (or a set of constraints), including a variety of different types of objective functions and different types of domains.
