Course ‘Data Structure and Algorithm Analysis’ - Course instruction with C/C++ implementation of the fundamental data structure and algorithm in the syllabus.

Data Mining Group, Innovative Software Technology Development Center - Propose a novel Social Network Recommendation Algorithm using Laplacian Matrix based on the affinity among users, tags and images, formulate the optimal function in generalized eigen-system, and verify its better performance against several popular methodologies on self-crawling data from Flickr; - Research on 9sky online music radio recommendation project. Introduce an efficient hierarchical algorithm to handle massive click through and frequent queries for personalized music recommendation. Commercial product integrated with our recommendation system will be published soon; - Reduce the feature selection problem to a combination of Quadratic/Linear Programming problem by introducing innovative metric. The algorithm is proved more effective compared to several state-of-the-art approaches.
