度量

Risk measurement is the foundation and hardcore of financial market risk management.

风险度量是金融市场风险管理的基础和核心。

Based on the C language implementation of the hash table algorithm code, a good understanding of the hash table and its time complexity measure.

详细说明：基于C语言编写的哈希表算法的实现代码，可以很好的理解哈希表及其时间复杂度的度量。

A gradient-based face recognition method using Partial Hausdorff Distance measure is proposed in this paper.

本文提出了一种新的基于梯度图像及 PHD 距离度量的人脸识别方法。

First, in order to achieve a performance independent of lighting conditions, the image is transformed into a Gradient Map. And then, Hausdorff distance measure is introduced to calculate the dissimilarity between two Gradient Maps.

首先，为了克服光照变化的影响，人脸图像被转换为梯度图像，然后，引入 Hausdorff 距离度量用于计算梯度图像之间的距离。

In Chapter One,we find the relationship between strong open set condition , Hausdorff dimension,the positivity of the Hausdorff measure and β space of graph-directed self-similar sets in complete metric spaces.

在第一章中，我们讨论了在度量空间中，图定向自相似集的强开集条件、Hausdorff维数，正的Hausdorff测度和β空间之间的关系。

Where d∞ is the uniformly Hausdorff metric.

这里 d∞是一致 Hausdorff 度量。

In classifier 3, HAVNET is used as the first stage and a multilayer neural network as the second. HAVNET is a kind of binary pattern classifier, which employs Hausdorff distance as similarity metric. The network architecture is flexible enough to incorporate self-supervised learning, self-organization, and competitive learning as required by specific application.

HAVNET是以Hausdorff距离为相似性度量的二值模式分类器，其网络结构具有相当的灵活性，可以在训练过程中采用自监督、自组织和竞争学习，在网络中用独立的通道表示一个类别中的各子类别模式，该特性使HAVNET在实现模式识别任务时，具有较强的可行性。

The hierarchical structure of the retrieval strategy is analyzed to reach the real-time and retrieval accuracy requirement. A trademark image database system under hierarchical scheme is implemented: the string-matching method is first used to reduce the image search scope under man-machine interaction, then smallest enclosed rectangle and Hausdorff distance metric are used to measure the similarity between trademarks under image region normalization and transform invariance.

2分析了层次结构的检索策略以解决图象检索的实时性要求和准确性要求，并实现了一具体商标库检索系统的层次检索方法，在人机交互方式下，用字符串匹配方法减少图象搜索范围；在图象区域规格化下，用最小约束距和Hausdorff距离度量商标相似性，并实现了变换不变性。

Another is that problems which involve cultural values sometimes have less to do with concrete objects, which can be measured and weighed, than with the superiority of certain mental states to others;and such states are notoriously hard to describe.

原因之一是诗的范围太广，其功用又多种多样；第二个原因是文化价值所涉及的常常不是可以直接度量的具体事物，而是某些精神状态的优劣比较；第三个原因是任何有关价值的问题，一旦深入讨论，都易于陷入哲学上的怀疑。

It is proved that if a homeomorphism f on a compact metric space with the POTP is distal homeomorphism, then f does not have the average shadowing property.

证明了紧致度量空间中有伪轨跟踪的distal同胚不具有平均跟踪性，并给出了有平均跟踪性的同胚是极小的一个充分条件。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
