Interests Brief Biography Research Work Publications
Data Mining: I focus on developing alternative clustering algorithms for fast-evolving stream data. I'm also interested in areas of uncertain data mining and ant colony clustering.
Heuristic Search: I focus on applying Ant Colony Optimization algorithms to problems arising in software requirement engineering.
I'm a third year Master
student in School of Software, Dalian University of
Technology (DUT). I work in OSCAR Lab (Optimizing Software by Computation from ARtificial intelligence). My advisor is Dr. He Jiang. I obtained
my Bachelor degree in Software Engineering (Sept. 2005 -
Jul. 2009) in DUT.
My Curriculum Vitae is here [CV].
Alternative Clustering on Stream Data: We issue the new problem of alternative stream clustering, which aims to find two high quality and dissimilar macro-clusterings in a given data stream. To tackle this new task, we propose a new algorithm named AltStream consisting of two components.
A Hybrid ACO Algorithm for the Next Release Problem: Next Release Problem (NRP) is a NP-hard problem in requirement engineering. It seeks to to balance customer requests, resource constraints, and requirement dependencies by requirement selection. To tackle large NRP instances, we propose a new algorithm named Hybrid ACO (HACO).
For more information about NRP, please refer to the supplement materials presented by Dr. Jifeng Xuan in OSCAR Lab.

The following is about my seminar presentations to OSCAR members. If you are interested in any of them, please contact me by email for a copy.
2011-07-29 AltStream, HPStream and DenStream: It's about three algorithms for stream clustering. AltStream aims to find two results while HPStream and DenStream only return on single clustering. [Abstract]
2011-04-21 A Framework for Alternative Clustering on Stream Data: It's an initial framework for alternative stream clustering. Some improvements were made later. [Abstract]
2010-11-30 Alternative Clustering on Stream Data: The feasibility of finding alternative clustering on stream data was analyzed here with some real-world examples. The methods to compare two clusterings were also presented. [Abstract]
Alternative Clustering: It's about four alternative clustering techniques on traditional datasets, including COALA, Multi-view, ADFT and Constraint optimization. [Abstract]
2010-06-18 Uncertain Data Mining: It's about a literature investigation of uncertain data mining, including clustering, classification, frequent item set mining, and outlier detection. [Abstract]
2010-06-04 Semi-Supervised Clustering with Constraints: It's about constraint clustering, including COP-kmeans, distance metric learning, EM and HMRF Model. [Abstract]
2010-01-08 A Hybrid ACO Algorithm for the Next Release Problem: It's about the ACO algorithm for NRP problem with the parameter tuning procedure CALIBRA. [Abstract]
