Research Experience
Center-Piece Subgraph	Proposed a fast solution to center-piece subgraph: given Q queries nodes, we want to find the nodes and the resulting subgraph with some budget b that have strong connection to all or most of query nodes.
Fast Random Walk with Restart	Proposed a fast solution to do random walk with restart.
Learn from Graph	Mainly focusing on 1) investigating transductive inference for multi-modality by graph model; 2) a unified framework for transductive inference on graph model
Image Retrieval	Mainly focusing on 1) automatic keyword annotation for large image database; and 2) unified learning in image retrieval. Proposed 1) a manifold-ranking based keyword propagation method; 2) an optimization method based on graph model to unify low-level feature, on-line relevance feedback and off-line long term learning.
Blur Detection	Proposed an effective and computing efficient algorithm to 1) judge whether or not a given digital image is blurred and 2) determine to what extent it is blurred. The proposed technology might be adopted and transferred to product in Microsoft Research Asia.
Image Quality Assessment	Proposed a unified learning-based framework for No-Reference image quality assessment. The proposed framework contributes to No-Reference image quality assessment mainly in three parts: 1) providing a general solution for distortion measurement; 2) making a first attempt for holistic quality evaluation; and 3) unifying the above two.
Anomaly Detection in Network	Mainly focusing on applying fusion technology (such as boosting, multi-view learning, etc.) into these fields. Proposed 1) Kernel principle component classifier for anomaly detection 2) Introducting boosting technology into anomaly detection.
Internet Traffic Prediction	Introduced and designed some specific versions of boosting algorithm for self-similar and non-linear Internet traffic prediction.
Simulated Annealing Algorithm	Proposed two improved versions of simulated annealing algorithm for Travel Salesman Problem (TSP)
