摘要: 现有的聚类算法比如 CluStream 是基于 k-means 算法的。这些算法不能够发现任 意形状的簇以及不能处理离群点。 解决上述问题,本文提出了 而且, 它需要预先知道 k 值和用户指定的时间窗口。 为了 分将数据映射到一个网格, D-Stream 算法,它是基于密度的算法。这个算法用一个在线部 在离线部分计算网格的密度然后基于密度形成簇。 度衰减技术来捕获数据流的动态变化。 为了探索衰减因子、 数据密度以及簇结构之间的关系, 我们的算法能够有效的并且有效率地实时调整簇。 群点的稀疏网格是合理的, 算法采用了密 而且, 我们用理论证明了移除那些属于离 从而提高了系统的时间和空间效率。 该技术能聚类高速的数据流 而不损失聚类质量。 实验结果表明我们的算法在聚类质量和效率是有独特的优势, 并且能够 发现任意形状的簇,以及能准确地识别实时数据流的演化行为(Abstract: Existing clustering algorithms such as CluStream are based on the k-means algorithm. These algorithms can not be found Meaningful clusters and can not handle outliers. To solve the above problems, this paper presents)

说明：  These exercises and projects were originally the even-numbered exercises in the first edition. (The first edition did not distinguish between exercises and programming projects.) For the benefit of readers who have the first edition, the original exercise number is given in square brackets. For example, the notation [was #4] indicates that the number of the exercise (or programming project) was 4 in the first edition. If an answer is different because of second-edition changes, the word "modified" will appear inside the brackets: [was #4; modified].These exercises and projects were originally the even-numbered exercises in the first edition.

说明：  《MATLAB数值分析与应用(第2版)》重点讲述数值分析的思想和原理并图示其结果，尽可能避免过深的数学理论和过于繁杂的算法细节，有助于读者更有效地利用MATLAB的超强功能，来处理科学计算问题。《MATLAB数值分析与应用(第2版)》可作为各科学和工程专业本科生或研究生“数值分析”课程的教材或参考书，也可作为科技人员和计算机爱好者使用MATLAB的参考工具书。("Matlab numerical analysis and application (2nd Edition)" focuses on the idea and principle of numerical analysis, and illustrates the results, so as to avoid too deep mathematical theory and too complicated algorithm details as far as possible, which helps readers make more effective use of the super function of MATLAB to deal with scientific calculation problems. Matlab numerical analysis and application (2nd Edition) can be used as a teaching material or reference book for undergraduate or graduate students of science and engineering, and also as a reference book for scientists and computer enthusiasts to use MATLAB.)

“六度空间”理论又称“六度分隔”理论，可以通俗的阐述为“你和任何一个陌生人之间所间隔的人不会超过六个人”，也就是说最多通过五个人你就能认识任何一个陌生人。(" Six Degrees of Separation" theory known as " six degrees of separation" theory, can be described as a popular " people between you and any stranger spaced no more than six people," that is up to you by five people will be able to recognize any stranger.)
