Restarted Accelerated Primal-Dual Algorithms with Adaptive Stepsizes for Nonlinear Conic Constrained Convex Optimization
Necdet Serhat Aybat, Jinxin Wang
We propose restarted accelerated primal-dual algorithms with (non-monotone) backtracking (rAPDB) for convex nonlinear conic programs, with quadratically constrained quadratic progr…
Randomized Submanifold Subgradient Method for Optimization over Stiefel Manifolds
Andy Yat-Ming Cheung, Jinxin Wang, Man-Chung Yue +1
Optimization over the Stiefel manifold is a fundamental computational problem in many scientific and engineering applications. Despite considerable research effort, high-dimensiona…
On the Estimation Performance of Generalized Power Method for Heteroscedastic Probabilistic PCA
Jinxin Wang, Chonghe Jiang, Huikang Liu +1
The heteroscedastic probabilistic principal component analysis (PCA) technique, a variant of the classic PCA that considers data heterogeneity, is receiving more and more attention…
Projected Tensor Power Method for Hypergraph Community Recovery
Jinxin Wang, Yuen-Man Pun, Xiaolu Wang +2
This paper investigates the problem of exact community recovery in the symmetric -uniform hypergraph stochastic block model (-HSBM). In this model, a -uniform…
Decentralized Weakly Convex Optimization Over the Stiefel Manifold
Jinxin Wang, Jiang Hu, Shixiang Chen +2
We focus on a class of non-smooth optimization problems over the Stiefel manifold in the decentralized setting, where a connected network of agents cooperatively minimize a fin…
Orthogonal Group Synchronization with Incomplete Measurements: Error Bounds and Linear Convergence of the Generalized Power Method
Linglingzhi Zhu, Jinxin Wang, Anthony Man-Cho So
Group synchronization refers to estimating a collection of group elements from the noisy pairwise measurements. Such a nonconvex problem has received much attention from numerous s…
Joint Bandwidth Allocation and Path Selection in WANs with Path Cardinality Constraints
Jinxin Wang, Fan Zhang, Zhonglin Xie +2
In this paper, we study a joint bandwidth allocation and path selection problem via solving a multi-objective minimization problem under the path cardinality constraints, namely MO…
Sparse High-Order Portfolios via Proximal DCA and SCA
Jinxin Wang, Zengde Deng, Taoli Zheng +1
In this paper, we aim at solving the cardinality constrained high-order portfolio optimization, i.e., mean-variance-skewness-kurtosis model with cardinality constraint (MVSKC). Opt…
