WebMay 18, 2024 · Statistically, the sparsity of solutions often leads to better model interpretability and prediction [ 20 ], and empirically the sparsity of the signals have been observed. Thus sparsity constraint represents a natural piece of a priori knowledge for solving inverse problems. In the framework of Tikhonov regularization, such a priori … WebJul 22, 2024 · Bangti Jin received the B.Eng. degree in polymeric materials and engineering in 2002, theM.Sc. degree in computational mathematics in 2005, both from Zhejiang University, Hangzhou, China, and the Ph.D. degree in applied mathematics from the Chinese University of Hong Kong, Hong Kong, in 2008.
