随机森林
说明: 随机森林算法与 Bagging 算法类似,均是基于 Bootstrap 方法重采样,产生多个训练集。不同的是,随机森林算法在构建决策树的时候,采用了随机选取分裂属性集的方法
本程序中,将乳腺肿瘤病灶组织的细胞核显微图像的 10 个量化特征作为模型的输入,良性乳腺肿瘤和恶性乳腺肿瘤作为模型的输出。用训练集数据进行随机森林分类器的创建,然后对测试集数据进行仿真测试,最后对测试结果进行分析。(Similar to bagging algorithm, random forest algorithm is based on bootstrap resampling to generate multiple training sets. The difference is that the random forest algorithm uses the method of randomly selecting the split attribute set when constructing the decision tree
In this program, 10 quantitative features of nuclear microscopic image of breast tumor tissue are taken as the input of the model, and the benign and malignant breast tumor are taken as the output of the model. The training set data is used to create the random forest classifier, then the test set data is simulated and the test results are analyzed.)

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)
