查询词典 metric

Because of the difference of its metric from Euclidean spaces, many essential concepts in Minkowski space change a lot. This makes the conclusions of some problems in Minkowski space much different.

由于度量的不同，导致了一些基本概念有了质的变化，使得Minkowski空间的一些问题与Euclidean空间相比有着出人意料的结论。

首先， 使用欧基里德距离量测法与动态时间扭曲法，测量出时间序列间的相似度。

However, most research results were on the ideal condition that geographical space was a homogeneous one, and almost all spatial analysis methods are according to the metric of planar Euclidean distance, its drawback is quite obvious.

但是，目前多数研究都假设地理空间是一个均质空间，采用基于平面欧氏距离的空间分析方法，这是有局限的。

"Two- and three-dimensional Euclidean spaces are metric spaces, as are inner product spaces, vector spaces, and certain topological spaces."

二维和三维的欧几里德空间是度量空间。另外，内乘空间、向量空间以及某些拓扑空间等也都是度量空间

In the first step, we set up a feature vector database, then we use Euclidean distance metric and a three-layer BP neural net to recognition.

在识别阶段，首先使用欧式距离进行特征矢量之间的匹配来识别，然后考虑到神经网络在处理诸如学习、理解等问题具有的优越性，又采用了神经网络方法进行识别分类，论文中采用一个三层前馈神经网络，权值调整使用BP算法。

Using colour systems such as is computationally prohibitive, but in practice it is adequate to use a Euclidean distance metric in components coded nonlinearly according to video practice.

使用如CIE L*u*v*或 L*a*b*的色度系统，计算是不允许的。但实际上，依据视频实践，在R'G'B'分量非线性编码时，使用欧机里德距离度量是适当的。

And a solution for crowd path navigation based Voronoi diagram is presented. By making use of the ability that the Voronoi diagram partitions the space according to the Euclidean metric, the path planning with collision avoidance is achieved by forbidding agents to move outside their Voronoi regions.

利用Voronoi图对平面按照欧式距离进行划分的特性，并通过将每个虚拟人的Voronoi区域作为其活动范围，使每个虚拟人都限制在自己的区域内活动，从而在人群路径规划中避免了为虚拟人进行碰撞检测的复杂操作。

The new IRS algorithm has greatly improved the approximation performance of the original reduced set method by embedding a new distance metric called image Euclidean distance into the kernel function.

其中，所谓IRS算法是指在精简集算法的核函数中嵌入一种新的距离度量——图像欧式距离——来改善其迭代近似性能，IRS可以有效地生成新的、位于类别边界附近的虚拟样本以增强给定训练集。
