Juncai He

Juncai He is affiliated with King Abdullah University of Science and Technology (KAUST) in the Computer, Electrical and Mathematical Sciences and Engineering Division, with additional connections to Hebei Agricultural University in China. His research spans theoretical machine learning, mathematical optimization, and practical applications in earth system science and natural language processing.

Dr. He's research focuses on the mathematical foundations of deep learning, particularly examining the expressive power of ReLU networks and geometric properties of manifold-structured data. His work demonstrates strong theoretical rigor while maintaining practical relevance, as evidenced by applications in earth system forecasting and LLM-generated text detection. Recent publications show increasing interest in multiscale analysis techniques and optimization methods for complex data structures.

His collaborative network includes significant partnerships with Liangchen Liu and Richard Tsai (Yen-Hsi Richard Tsai), with whom he has published multiple papers on manifold learning. Additional collaborations with Guangsheng Bao, Yanbin Zhao, and Yue Zhang indicate expanding research interests in large language model security and detection techniques.
