Prospective students

I am looking for 2 motivated master's students at the School of Artificial Intelligence, Shenzhen University.

Strong mathematics and a solid understanding of deep learning fundamentals are especially welcome. I offer hands-on research guidance and computing resources. Outstanding students may be recommended for joint Ph.D. opportunities with Peng Cheng Laboratory and Harbin Institute of Technology, Shenzhen, subject to the relevant admission requirements.

Please email me with your CV and a brief description of your research interests. jsl@szu.edu.cn

Research interests

• Trustworthy learning. Semi-supervised learning, pseudo-label selection, and uncertainty estimation.
• Visual perception. Image, video, and 3D segmentation; occlusion and incomplete observations.
• Multimodal understanding. Representation learning across vision, language, and structured information.
• Structured modeling. Connecting visual perception with mechanism-based models for complex systems.

Current focus (2024–present): Domain generalization & test-time adaptation; learning with noisy labels & knowledge distillation; LLM hallucination detection.
