分类数据

On account of inaccurate classification, the traditional hierarchical Webpage recommendation algorithm based on vector space model can not produce high precision when it deals with large amounts of data.

在面对大数据量时，传统的基于VSM的分层网页推荐算法由于分类的不准确，造成推荐精确率较低。该文针对这个缺陷提出了改进的分层推荐算法，该算法在推荐过程中综合考虑了领域和用户兴趣，以及网页和用户兴趣的相似程度，来为用户提供高效的个性化网页推荐。

Should actively create conditions for the establishment of quality management microcomputer database;the original records and classification of account must be clear, such as fill, shall not be altered, when the slip of the pen should be used in the central mistake a few strokes "=" and write correctly in their top of the figures and affix the seal rewriter;the quality and timely analysis of test data to collate, conducted quarterly summary, year-end summary.

要积极创造质量管理微机数据库的建立情况；原记录和账户的分类必须清楚，如实填写，不得涂改，当笔误，应在中央犯的错误使用几笔"="，写在他们的正确的数字顶部并加盖印章的改写；的质量和测试数据进行及时分析整理，每季进行一次总结，年终总结。

Bayesian network is composed of directed acyclic graph and probability chart; it can modify the prior probability density dynamically and improve the accuracy of classification.

该文介绍了利用贝叶斯网络对遥感数据进行分类处理的算法和技术过程。

Data mining is an important part of AI and classification is a kind of useful application.

数据挖掘是人工智能中知识发现的重要组成部分，而分类又是一种主要的应用形式。

The field in this database can be sorted either alphabetically or by date of entry.

Range image process algorithms were investigated in the paper, which can be used to extract some features from airborne laser scanning altimetry data based on range data or intensity data of laser.

本文提出并研究了基于机载激光扫描测高数据提取建筑物的理论和方法，提出了基于分类分割后的原始激光脚点数据的提取规则房屋的方法。

Reports and data provided include: downloadable annotated reports with data relating to the water quality (including trace metal concentrations) of the Forth Estuary between the years 1980-99, water quality standards for various coastal stretches in East Scotland, water quality classification schemes and resultant data (excellent - poor) for rivers, estuaries and coastal waters, bathing water data (1998 - 2001), SEPA indicator measurements for surface water quality, and a national archive of water quality data taken from 230 sites around Scotland which is used to estimate the river-borne input of selected contaminants to the sea and investigate long-term trends in main determinands.

其中包括：可下载报告全文，并带有1980-1999年Forth河口水质的相关数据，东苏格兰海岸不同的水质标准，水质分类方案及河流、河口、沿海、浴水的合成数据（1998-2001年），苏格兰环境保护机构的地表水质指示剂测定法和国家水质档案资料（水样取自苏格兰各地230个点位，常用于估计河流承受的污染物输入和调查长期趋势）。

We applied the model to analyze the expression data set of leukaemia. The experimental result proved that this model can get cluster numbers automatically and a high accuracy of classification.

将该种模型运用于公开的白血病基因表达数据集进行实验，实验表明该方法能自动获取基因表达数据的聚类数，并得到较高的分类准确率。

When one rule is generated, boosting mechanism is used to change the weights of the training instances so as to mine new rules that are focused on currently uncovered or misclassified instances.

Boosting机制用于调整训练数据的权值，使得新生成规则集中于当前未被覆盖或误分类的数据实例。

The split between the two groups can hardly be papered over.
