(12月19号)Sparse coding: Models, algorithms and applications

Sspeaker：Prof.Ji Hui(National University of Singapore)Title: Sparse coding: Models, algorithms and applicationsAbstract: In recent years, sparse coding has been widely used in many applications ranging from image processing to pattern recognition. The basic concept of sparse coding is to learn an over-complete dictionary from data over which the data can be spa...

(12月28日）Holder estimates for homotopy operators on strictly pseudoconvex domains with C^2 boundary

Title: Holder estimates for homotopy operators on strictly pseudoconvex domains with C^2 boundarySpeaker: Professor Xianghong Gong (University of Wisconsin-Madison)Abstract: We derive a new homotopy formula for a strictly pseudoconvex domain of C^2 boundary in the complex Euclidean spaces for the d-bar operator. We obtain estimates for th...
