Caijun Sun, a PhD Candidate


I'm Caijun Sun and at present a PhD candidate at State Key Laboratory of Networking and Switching Technology(SKLNST) in Beijing University of Posts and Telecommunications(BUPT) starting from Fall 2015. Before that I finished my master courses in Information Security from BUPT under the supervision of Dr. Wen Qiaoyan. I am currently working for Network Security Research Center(NSRC) at SKLNT with my advisor Dr. Qin Sujuan. A primary thrust for my current and future work focuses on developping data mining and machine learning algorithms in social informatics and NLP(Natural Language Processing).

姓孙,名才俊,字江南, 从本科开始接触编程,到现在也有若干个年头,跟大部分的互联网从业者相似,业余时间也喜欢写写代码,丰富下枯燥的生活。平时爱好比较广泛,喜欢涉猎一些互联网发生的新奇事物,如比特币,可惜入场太晚,不过与传统的玩家不同,现在已经转战量化交易;也有空没空收藏一些域名,从一无所知的小白,到后面小赚一笔,至今手头还有留存不少域名,当然,收藏为主,卖的少数。当前状态为博士科研狗,主要兴趣方向为社交媒体挖掘,自然语言处理,不过当前水平还是菜鸟中的菜鸟,本博客用于整理个人学习过程中的所思所想,本着原创的精神,所有博客中的内容都是个人挖掘出来的东西,宁缺毋滥。
