Research Groupssee more >>

• Machine Learning Research Group

    

  Mainly focus on some fundamental problems in machine learning and computer vision, especially including: self-paced learning, noise/loss modeling and tensor sparsity.

• Big Data Software and Hardware Platform Research Group

    

  Our research team focuses on the distributed systems and platforms for big data acquisition, management，and processing, including system architecture, resource management and scheduling, and distributed computing and networking. Specifically, we are focusing on the joint optimization of big data systems and analytical algorithms, algorithms for text stream processing and analysis, and big data acquisition and processing with the edge and fog architecture.

• Deep Learning and Image Processing Research Group

    

  This group focuses on the following two research directions. (1) Model-driven deep learning approach, that combines the metrits of mathematical modeling of physical mechanism and data-driven deep learning approach. (2) The fundametal algorithms in medical image anlaysis, including image reconstruction (MRI, CT, etc.), lesions detection, and multi-model image registration, etc.
