Data mining


不要自己做Arff文件,麻烦,你做成.csv,让weka自己另存为就行了。 文本文件打开,把字段名复制到第一段,保存成.csv 举个例子: @RELATION cars @ATTRIBUTE buying REAL @ATTRIBUTE maint REAL @ATTRIBUTE doors REAL @ATTRIBUTE persons REAL @ATTRIBUTE lug-boot REAL @ATTRIBUTE safety REAL @ATTRIBUTE class {unacc,acc,good,v-good} @DATA vhigh,vhigh,2,2,small,low,unacc vhigh,vhigh,2,2,small,med,unacc vhigh,vhigh,2,2,small,high,unacc vhigh,vhigh,2,2,med,low,unacc vhigh,vhigh,2,2,med,med,unacc vhigh,vhigh,2,2,med,high,unacc vhigh,vhigh,2,2,big,low,unacc vhigh,vhigh,2,2,big,med,unacc 然后用Weka打开就可以了。

如何将UCI的.data转成arff?

分类挖掘在图像识别领域的应用 韦国华 (中国科技技术大学 软件工程硕士 上海四期班, 上海 200333) 朱  明 (中国科技技术大学 自动化系, 安徽 合肥 230051) 摘要:视频处理和识别系统是一个较为复杂的计算机软件系统。其处理和识别的结果需要有一个好的可信性分类方法和一个自动化分类工具。目前我们在一些系统上仍然需要人工干预来实现整个系统的完整运行和执行,然而人工的干预工作量大,其判别结果易受人为因素的影响很大,且存在视觉易疲劳和检测速度缓慢等问题,给最终的结果带来很大的干扰。这里我们介绍一种针对一些特定的图像段按色差自动分类的方法,使用从室外采集到的一些随机图像样本实例及其已知的特征数据,将各个图像段进行分类,并对其结果作出客观评估,为提升识别率提供依据。 关键字:数据挖掘;图像处理;分类挖掘 Classification mining in the field of image recognition Wei Guo Hua1,  Zhu Ming2 (1.Department of Automation, University of Science and Technology of China, Shanghai, China; 2.

数据挖掘小论文 My draft version of data mining course thesis


本来我想用前面那个Human Activity Recognition Using Smartphones Data Set来完成我的Data mining的结业小论文,但后来在将该Dataset转换为Weka的arff格式时碰到点问题,所以就放弃了,最终将以下面这个Image Segmentation Data Set来写,同时相对来说,这个Dataset也跟我的工作更加相关、相近一些。 本Dataset源于:http://archive.ics.uci.edu/ml/datasets/Image+Segmentation
