About Me

Welcome to Lingkai Kong (孔令恺)’s homepage! I am a Ph.D student in the School of Computational Science and Engineering at Georgia Institute of Technology. I am working with Prof. Chao Zhang. I recieved my B.E. in Information Engineering from Southeast University.

My research spans across machine learning, natural language processing and data mining. I am particularly interested in making trustworthy intelligent system in open-world settings. Toward this goal, I am currently working on the following research thrusts:

  • Uncertainty quantification and out-of-distribution detection in deep learning;
  • Out-of-distribution generalization and zero shot learning;
  • Application of uncertainty-aware deep learning in natural language processing and healthcare.
