摘要：今晚读了Jiawei Han团队的一篇paper，就网络社群的异常点检测算法进行了学习。传统的发现算法归结为全局异常点检测算法和直接相邻异常点检测算法，韩的方法是基于“信息+社区结构”的Community Outlier Detection Algorithm，后面试试看是否可借用来识别特定事件的网络水军群体。根据Jing Gao, Jaiwei Han等人发表的On community Outliers and their Efficient Detection in Informaiton Networks文章，传统的网络社区异常点检测算法（Community Outlier Detect 阅读全文

摘要：关注Hbase较长时间了，去年放了一段，今年项目中打算采用HBase，近期发现，Hbase的英文书已经出来了。There may be many reasons that brought you here, it could be because you heardall about Hadoop and what it can do to crunch petabytes of data in a reasonableamount of time. While reading into Hadoop you found that for random access to theaccumul 阅读全文
