Bio

Welcome to my homepage! I am Tianxiang Zhao, a PhD student in the Pennsylvania State University, and co-advised by Prof.Xiang Zhang and Prof.Suhang Wang.

Research

My research focuses on topics related to data-centric machine learning. Most recently, I am interested in the following topics,

  • Learning with weak supervisions:
    • Few supervision: semi-supervised and unsupervised learning;
    • Low-quality supervision: learning with noisy labels;
    • Biased data: alleviating biases and demographic unfairness in the learned model.
  • Uncovering knowledge learned by the model:
    • Prediction and explanation co-design for intrinsically interpretable models;
    • Post-hoc explanation of a trained existing model.
