Current Research Themes:

A. Massively Parallel Data Mining

We are exploiting the latest GPU computing architecture (CUDA 7.X and NVIDIA Kepler K80) to generate highly efficient (one to two orders of magnitude faster) and effective (more precise and robust) solutions for tackling large scale real-world data mining and optimization problems.

We are proud to host the NVIDIA GPU Education CenterAward  Poster 1  Poster 2

B. Efficient Clustering Using Boundary Information

We are investigating clustering techniques based on the boundary information of data clusters. Instead of having all the raw data involved in the clustering process, only a small portion of data (5%-10%) is strategically extracted and fed into the traditional clustering method, which can dramatically improve the efficiency of clustering algorithms without compromising the quality of clustering.

C. Robust Clustering in Strong Noise Settings

We are investigating clustering techniques capable of discovering complex clusters in datasets with significant level of noise (80%). We employ density based multiscale analysis and various statistical techniques to reliably identify noisy objects from "clustered" objects.

Recent Research Theme:

Vision based dynamic hand gesture recognition for touchless human computer interaction.

We developed robust vision based hand gesture recognition techniques using optical cameras, Kinect and Leap Motion, which are capable of reliably detecting, tracking and recognizing flexible human hand gestures under complex environments (unfavorable lighting conditions, occlusions and background noise) and have found exciting applications in our everyday life (smart TV, smart phone, virtual reality and computer games).
