Research interests and group

Machine learning and data mining, with a focus on sequence, graph, and probabilistic modeling:

• Time series data and spatiotemporal data modeling.
• Self-supervised learning, structured and interpretable representation learning.
• Graph and compact deep learning by exploring the underlying symmetry and structures.
• Probabilistic generative models.

You can learn more about me from my posts.

I am very glad to work with some excellent students at HITSZ. Self-motivated undergraduate students with strong programming skills and solid math background are welcome, feel free to drop me an email and attach your cv if you are interested.
