Alumni Profile: Bin Jiang, Computer Science

October 10, 2011

You could say that Dr. Bin Jiang's career is based on uncertainty.

He did his bachelor's degree in Computer Science at Peking University, then moved to Australia to do his master's degree at the University of New South Wales. He then came to SFU in 2008 and finished his PhD this year. Clearly, he was always certain about his academic path.

His research was about analyzing large amounts of data to extract useful knowledge. At SFU, he worked in the data mining lab with his supervisor Dr. Jian Pei, focusing on data mining uncertain data. This analysis has huge implications in social networks, which constantly generate massive amounts of uncertain data at explosively high speeds.

His PhD thesis, Summarizing certainty in uncertain data, describes the algorithms he developed to conduct data mining tasks, such as clustering and outlier detection, on large uncertain data sets. It's led to research papers which were published in premier international conference proceedings and journals, such as ACM SIGKDD Knowledge Discovery and Data Mining (KDD), International Conference on Very Large Data Bases (VLDB), IEEE International Conference on Data Engineering (ICDE) and IEEE Transactions on Knowledge and Data Engineering (TKDE). (See his SFU website for links to the papers.)

As part of his PhD work, he interned for 6 months at Microsoft Research Asia, working on emerging data intensive applications by analyzing large Bing search logs. He also prototyped an automated search task suggestion system — through analyzing search queries for tasks such as purchasing airline tickets or booking hotels, the system can identify the user's search task and suggest the best queries to complete the task. 

He's just moved to California to work at Facebook. The company's mission, to help people to share and connect, generates massive amounts of data which requires smart systems to bring users relevant stories. His data analysis skills will help Facebook's computers filter out the uncertainty of "user noise" and deliver correctly related content.

One thing is certain: Bin's having a great time and looking forward to solving more uncertain challenges.
