The vq - based approach assumes a gaussian mixture distribution , which fits real - world image data reasonably well . after estimating this distribution through em method , this approach trains optimized vector quantizers to partition data space 该方法使用更适合真实图像库的高斯混合模型描述数据分布,并训练优化的矢量量化器划分数据空间。
Fixing the applied program in the external data space of the dsp and collocating the frame - memorize as the program space of the dsp , therefore the conflicts that there is not enough data space in the dsp for a lot of video data was resolved 将应用程序固化在dsp的外部数据空间,将帧存配置为dsp程序空间,解决dsp数据空间小而视频数据量大的矛盾。
In the new architecture , the data space is substituted by dw , the user space is replaced by olap , the method space is added by dm . furthermore , the connection between the three spaces is analyzed 用数据仓库作为数据空间的主要组成部分,将olap用于用户空间,利用dm技术改进方法空间,并对三空间的联系和影响进行了分析,以突出其独特的性能优势。
The dm642 uses a two - level cache - based architecture , level 1 cache is composed of a 16 - kbit l1p ( level 1 program cache ) and a 16 - kbit l1d ( level 1 data cache ) , level 2 cache consists of 256 - kbit memory space that is shared between program and data space 同时,研究了消除欠采样噪声算法,并实现其处理功能。本文提出的系统设计方案,实现了高速、稳定、灵活的视频采集处理播放平台,可以高速而稳定的持久运行,达到了设计的要求。
Data warehouse is a hot research area in 90s its main motif is to provide the decision - maker a powerful tool : gathering the data in pure consistent , relevant pattern , and making use of the data in managing analyzing , data - mining purposec that means that the decision - maker can use the tool to understand , grasp the situation of the business from different directions and forecast the future of it when using data warehouse , the processing speed determines data warehouse ' s practicability and processing ability the hoc ( highway decision center ) system realized before solves some key problems about intermediate scale data , mainly concentrating data warehouse performance coefficient when using hdc in large scale data , it encountered processing speed problem then the settlement of this problem becomes a major research point so , based on the former research achievements , the present task is to construct the renowned data warehouse architecture and its relevant algorithms , then adapts the system to the large scale dataset with data mining functions c this paper is a part of the research in order to construct the powerful system , a key problem is to cope with the processing - speed problem and the data space problem , etc , - caused by the large scale dataset and magnificent dataset this is also the core in the present data mining research this paper ' s motive is to design and realize a decision - tree classifier in the data warehouse system for large - scale dataset 大型数据仓库的处理速度问题目前是制约其推广应用的关键所在,也是这一领域的一个重要研究课题,也正是我们当前工作的重点:在前期研究工作的基础上围绕提高大型数据仓库处理速度问题,建立改进的数据仓库系统模型和相关算法,开发出面向中级以上企事业单位的、具有数据挖掘和分析能力的大型数据仓库系统。建立大型数据仓库所面临的关键问题,是如何妥善解决实际业务数据的大规模、海量特征所带来的处理速度和空间等问题,这也是当前挖掘技术研究必然面对的核心问题。本研究的目的是设计并实现大型数据仓库系统中的分类数据挖掘工具? ?决策树分类器,主要工作是在综合了解现有决策树分类算法的研究情况的前提下,对决策树算法适应大规模数据集的问题进行探讨,力求设计出能较好地适应大规模数据的分类器算法。
