About Me

I am Zifeng Wang, a third-year PhD student in Machine Learning at Northeastern University, advised by Prof. Jennifer G. Dy. I got my BS degree in Electronic Engineering from Tsinghua University, Beijing. My study and research interests mainly focus on machine learning, computer vision and various application of artificial intelligence. I believe AI would change the world ultimately.

Before entering Northeastern, I worked with Prof. Jiwen Lu on multi-object tracking by reinforcement learning. At summer 2017, I went to University of Michigan as a visiting researcher under the instruction of Prof. Jia Deng. Before that, I worked with Prof Shengjin Wang and Professor Yong Li on vision and big data respectively. During my exchange at Northeastern University, I worked with Prof. Jennifer G. Dy on machine learning. You could refer my curriculum vitae for further information.

Selected Projects

I have joined several research teams, from big data mining, computer vision to machine learning. These precious experiences taught me a lot.

Learn-Prune-Share for Lifelong Learning

Northeastern University, Advisor: Jennifer Dy
  • Incoporated the state-of-the-art Alternating Direction Method of Multipliers (ADMM) based pruning strategy to solve the lifelong learning problem.
  • Designed a novel knowledge sharing scheme, which learns to select useful knowledge from old tasks and adapt them to the current task.
  • Paper accepted at ICDM 2020, Learn-Prune-Share for Lifelong Learning
  • .

Class Discovery Kernel Network

Northeastern University, Advisor: Jennifer Dy
  • Proposed a deep learning framework which utilizes HSIC to bridge supervised and unsupervised information together in a systematic way.
  • Addresses the problem of overfitting to old classes, leading to improved class discovery, and can be generically applied to a broad array of deep architectures.
  • Best Paper Candidate at ICDM 2020, Open-World Class Discovery with Kernel Networks
