Data Mining Group

Research Interests

Our current research is mainly focused on some fundamental data mining research issues, such as complex knowledge mining from complex data (e.g., sequences, trees, and graphs) and their various applications, constrained pattern discovery, and scaling up data mining algorithms for huge data.
