Research Experience

Robust Training with Word-level Adversity for NLP
Sept.2017-April.2018   Advanced Integration and Mining Lab (AIM), Eugene, OR, United States of America
Advisor: Prof. Dejing Dou (Director) and Prof. Daniel Lowd

  • Proposed an efficient word-level gradient-based adversarial examples generation approach for training robust models.
  • Evaluated the method with convolutional neural networks across a wide range of sentence-level classification tasks and the method using adversarial training achieved excellent performances on benchmarks.
  • This work on Adversarial examples for NLP was featured in an article in The Register
  • Automatic Music Accompaniment Using Probabilistic Machine Learning
    Jul.2017-Aug.2017   The University of Hong Kong, Hong Kong S.A.R.
    Advisor: Prof. Francis Lau (Associate Dean)

  • Proposed a fast decoding algorithm to deal with performance errors and reduce computational complexity from O(n2) to O(n). It is able to work in real time with practical length scores.
  • Constructed a comprehensive system and developed a parallel Hidden Markov Model for score following.
  • Developed a new free open-source Windows-based automatic music follower and accompanist.
  • Express Bill Handwritten Telephone Number Recognition
    Feb.2017-Jul.2017   Learning And Mining from DatA Group, Nanjing University
    Director: Prof. Zhi-Hua Zhou (ACM, AAAI, AAAS, IEEE Fellow, Academy of Europe Foreign Member)

  • Incorporated an NLP lexicon-based transcription into an RCNN-CTC network and improved its performance on standard benchmarks.
  • Accomplished 95% accuracy on each digit and 90% accuracy on a series of telephone number.
  • Real-time 3D Surface Reconstruction Using Lidar (Light Detection And Ranging)
    Aug.2016-Sept.2017   Visual Sensing and Graphics Lab (VISG Lab), Nanjing University
    Supervisor: Prof. Sidan Du (Director)

  • Proposed a novel line of sight algorithm to real-time reconstruct surface and achieved state-of-the-art results.
  • Employed a new surface lattice data structure in implicit surface update for memory efficiency.
  • Presented a real-time 3D reconstruction pipeline for large-scale Lidar point cloud.
  • Implemented parallel computation to update the implicit surface faster and Motion Estimation and Mapping to register point cloud. [Report] [Video] [Demo]

    Leadership Experience

    Co-Founder of a Children Care Volunteer Program     Sep.2015-Dec.2015
    Co-founded a psychological consulting program to promote left-behind children growth and education. Volunteered to teach left-behind children Math and English in a junior high school located in the remote, underdeveloped Xiushui county. Recognized as a key team leader in the successful Warm One Hundred Campaign, which raised money for left-behind children. Our group received excellence award from China Foundation for Poverty Alleviation.

    Vice President of a Young Volunteers Association at Nanjing University     Jun.2015-Jun.2016
    Organized and participated in over 100 out-of-school and 20 in-school activities covering over 1000 volunteers. Our association received a volunteers association excellence award.
