Experimental results of customer churn prediction for a telecommunication carrier show that the proposed method is superior to original attributes and PCA feature abstraction in hit rate, covering rate, accuracy rate and lift coefficient, which indicates that KPCA abstracts nonlinear features of customer data and provides an effective measurement for customer churn prediction.
通过对某电信公司客户流失预测的试验结果表明：该方法获得的命中率、覆盖率、准确率和提升系数高于原始属性集和主成分分析特征提取法。这表明KPCA能提取客户数据的非线性特征，是研究客户流失预测问题的有效方法。

On the basis of analyzing the concepts of the information leveling, unified object-oriented modeling, data object self-description and abstraction of communication service mapping, etc., this paper expound how to use the model provided by standard IEC 61850 to build up object model of supervoltage protection IED from the aspects of functional definition, decomposition and allocation of application functions, object model of device and data object definition.
本文在分析IEC 61850标准的信息分层、面向对象的统一建模、数据自描述和抽象通信服务映射等概念的基础上，从功能定义、分解与分配、设备的对象模型、数据对象定义等方面阐述了如何利用IEC 61850提供的模型建立超高压线路保护装置的对象模型。
In this paper, we propose the formula to calculate the initial abstraction and potential maximum retention, as well as the soil type classified by soil texture and application of remotely sensed data.
本文分析了误差太大的原因，提出了对SCS模型产流计算的改进方法；并采用土壤质地分类，提出用混合聚类法进行土壤分类。
Proceed with warehouse current situation of the data, has stated the function of the data warehouse ofmarketing in the future emphatically; Second part Introduce marketing data basic conception involvedin the warehouse mainly, include some basic conception and basic operation mainly among them; Thethird part To marketing data abstraction of data of the warehouse mainly, marketing data of warehouseinclude marketing data of database of operating etc. mainly, the data to draw according to one basicmarketing basic function of Company mainly, with entering commonly, round pin, storing the systemthe samly, this text provides detailed procedure and data; Some data in the data warehouse ofmarketing come from the relevant theme in addition, a series of measures including the products, taking in the customer, rival and marketing mainly; Make a more detailed explanation to the enterpriselayer model of the data warehouse of marketing mainly with fourth part of this text, usually, the modelof a datum warehouse includes three big basic respects mainly: Conceptual model, logic model andphysical model.
从数据仓库现状入手，着重说明了未来营销数据仓库的作用；第二部分主要介绍了营销数据仓库中所涉及的基本概念，其中主要包括一些基本概念和基本操作；第三部分主要是对营销数据仓库中数据的提取，营销数据仓库中的数据主要包括操作型营销数据库中的数据，这部分数据主要是根据一个基本营销公司的基本职能进行提取，和通常的进、销、存系统一样，本文给出了详细的流程和数据；另外营销数据仓库中的一部分数据来自于营销过程与其相关的主题，主要包括营销的四个基本步骤和几个基本主题；本文的第四部分主要对营销数据仓库的企业级模型做一个比较详细的说明，通常，一个数据仓库的模型主要包括三个大的基本方面：概念模型、逻辑模型和物理模型。
If there is a defined function that can get the data you need, use it. Database abstraction (using functions instead of queries) helps keep your code forward-compatible and, in cases where results are cached in memory, it can be many times faster.
如果有一个定义过的函数可以得到你想要的数据，就用它，数据库提取对保证你的代码的向前兼容性有帮助，这样结果在内存中找到后，它可以用数倍更快的速度。
Elow the abstraction layer we have our Data Access Layer, this class is

This paper use H.264/AVC video transmission, which defines a set of three Profiles. Applications of the Baseline Profile include video telephony, video conferencing; applications of the Main Profile include television broadcasting and video storage; and the Extended Profile may be particularly useful for streaming media applications. H.264 proposes the idea of Network Abstraction Layer. The output of the encoding process of VCL data will be packeted into NAL units. The NAL will give the NAL units corresponding header information according the contents of the units.
而本论文在采用的多媒体压缩技术－H.264/AVC，其定义了三种不同的Profile：Baseline Profile著重在视讯电话，视讯会议等偏重即时传输等服务类别，Main Profile重点则是电视的播放以及影像储存的应用，而Extension Profile则是在串流媒体的播放上提供了较多的技术支援。H.264/AVC并且率先提出了网路提取层的概念，影像在视讯编码层完成编码之后，移交到网路提取层中，而网路提取层会依视讯编码层产生的编码内容将其封装近NAL units，并给予应有的标头资讯。

所以，你可以欣赏之间的OutlookGrid和实际数据抽象级别DataSourceManager（是的，我只是喜欢分层：-。
As a DMS always returns the information in the same format (a Data Graph), it hides the actual data storage and provides a level of abstraction between the SDO application and the EIS.
DMS总是以同一种格式（数据图）返回信息，它隐藏了实际的数据存储信息，在SDO应用程序和EIS之间提供了一层数据提取的功能。
