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.
