Analysis Accelerated Mirror Descent via High-resolution ODEs
Ya-xiang Yuan, Yi Zhang
Mirror descent plays a crucial role in constrained optimization and acceleration schemes, along with its corresponding low-resolution ordinary differential equations (ODEs) framewo…
Least Norm Updating Quadratic Interpolation Model Function for Derivative-free Trust-region Algorithms
Pengcheng Xie, Ya-xiang Yuan
Derivative-free optimization methods are numerical methods for optimization problems in which no derivative information is used. Such optimization problems are widely seen in many…
Linear Convergence of ISTA and FISTA
Bowen Li, Bin Shi, Ya-xiang Yuan
In this paper, we revisit the class of iterative shrinkage-thresholding algorithms (ISTA) for solving the linear inverse problem with sparse representation, which arises in signal…
Generalized truncated moment problems with unbounded sets
Lei Huang, Jiawang Nie, Ya-Xiang Yuan
This paper studies generalized truncated moment problems with unbounded sets. First, we study geometric properties of the truncated moment cone and its dual cone of nonnegative pol…
