Professor Xue-cheng Tai



Professor Tai Xue-cheng’s research has been focused on numerical mathematics and computational mathematics. In recent years, he has worked mainly on image processing, data analysis and machine learning problems. He is using numerical partial differential techniques for the application of image processing and data classification and extended these techniques to other modern applications. Robust and accurate models and fast, stable algorithms are some of the main concerns in his research.
