Handwriting recognition is difficult because of the high
variability of handwriting and because of segmentation errors.
We propose an approach that reduces this variability
without requiring letter...

基于斜率密度聚类的相似文本标定
抄袭检测 相似文本标定 聚类 指纹
2014/3/26
相似文本标定是抄袭检测的一个重要环节，现有标定方法大多采用直接对文本或指纹进行合并的方式，标定精度受干扰信息影响较大。针对这种局限性，分析了匹配指纹对的语义特征，提出基于斜率密度的相似文本聚类方法，将文本匹配合并问题转化成稠密样本点聚类问题，并在PAN公用语料库上对该方法进行了测试，得到的主要指标优于PAN10前3名。目前已将该方法用于华南理工大学特色专业教学平台的作业查抄，取得了较好的效果。
AS路径环路的研究
AS路径 RouteViews 路径环路 IPv6
2014/3/26
AS（自治域）路径环路是指在一个AS路径中出现相同的AS号且这2个或多个AS号是不相邻的。通过对RouteViews中统计的全球路由数据进行处理分析，统计了从2011年6月1日到2013年5月31日AS路径环路在IPv4和IPv6中每天发生的数量以及其在总路由条目中所占的比例。另外，统计了AS路径环路的持续时间分布以及前缀长度的分布。根据统计的数据，分析了AS路径环路发生的原因：路由信息不一致、跨...
