Research

My research interests are computer vision, machine learning. Specifically, I am interested in using deep learning to solve the practical problems in the industry such as the limitation of insufficient resources and a trade-off between computation and accuracy. My research focus is mainly on:

  • Neural architecture design and search

  • Network quantization

  • Network pruning

  • Knowledge distillation

  • AI embedded system

  • FPGA accelerator design of DNN
