The Influence of Boreal Summer Madden-Julian Oscillation on Precipitation Extremes in Indonesia
Fadhil R. Muhammad, Sandro W. Lubis, Sonni Setiawan
This study examines the influence of Madden-Julian Oscillation (MJO) on Indonesian precipitation during the extended boreal summer (May to September). The MJO is one of the dominan…
The springback penalty for robust signal recovery
Congpei An, Hao-Ning Wu, Xiaoming Yuan
We propose a new penalty, the springback penalty, for constructing models to recover an unknown signal from incomplete and inaccurate measurements. Mathematically, the springback p…
Balanced Augmented Lagrangian Method for Convex Programming
Bingsheng He, Xiaoming Yuan
We consider the convex minimization model with both linear equality and inequality constraints, and reshape the classic augmented Lagrangian method (ALM) by balancing its subproble…
Extensions of ADMM for Separable Convex Optimization Problems with Linear Equality or Inequality Constraints
Bingsheng He, Shengjie Xu, Xiaoming Yuan
The alternating direction method of multipliers (ADMM) proposed by Glowinski and Marrocco is a benchmark algorithm for two-block separable convex optimization problems with linear…
A Value-Function-based Interior-point Method for Non-convex Bi-level Optimization
Risheng Liu, Xuan Liu, Xiaoming Yuan +2
Bi-level optimization model is able to capture a wide range of complex learning tasks with practical interest. Due to the witnessed efficiency in solving bi-level programs, gradien…
An ADMM-Newton-CNN Numerical Approach to a TV Model for Identifying Discontinuous Diffusion Coefficients in Elliptic Equations: Convex Case with Gradient Observations
Wenyi Tian, Xiaoming Yuan, Hangrui Yue
Identifying the discontinuous diffusion coefficient in an elliptic equation with observation data of the gradient of the solution is an important nonlinear and ill-posed inverse pr…
Difference of convex algorithms for bilevel programs with applications in hyperparameter selection
Jane J. Ye, Xiaoming Yuan, Shangzhi Zeng +1
In this paper, we present difference of convex algorithms for solving bilevel programs in which the upper level objective functions are difference of convex functions, and the lowe…
A General Descent Aggregation Framework for Gradient-based Bi-level Optimization
Risheng Liu, Pan Mu, Xiaoming Yuan +2
In recent years, a variety of gradient-based methods have been developed to solve Bi-Level Optimization (BLO) problems in machine learning and computer vision areas. However, the t…
Bilinear Optimal Control of an Advection-reaction-diffusion System
Roland Glowinski, Yongcun Song, Xiaoming Yuan +1
We consider the bilinear optimal control of an advection-reaction-diffusion system, where the control arises as the velocity field in the advection term. Such a problem is generall…
