Research Experience
Distributed Best Subset Selection, 2022 - present
Proposed a two-stage distributed algorithm achieving minimax optimal rate with oracle property under \(\ell_0\) constraints.
Developed a data-driven Generalized Information Criterion for adaptive sparsity selection.
Result: arXiv:2408.17276
Communication-Efficient Decentralized Optimization, 2024 - present
Distributed Semismooth Newton Method, 2023 - present
Designed a dual-framework semismooth Newton solver for distributed sparse optimization.
Achieved linear convergence with only one vector transmission per iteration.
Demonstrated significant speed advantages over first-order methods and ADMM on Lasso and quantile regression.
Coordinate-wise ADMM (Co-ADMM), 2022 - present
Proposed a coordinate-wise ADMM for piecewise linear/quadratic + convex penalty optimization.
Achieved linear convergence with \(O(n)\) per-iteration complexity.
Developed a solver outperforming CVX, ECOS, and SCS on SVM, Huber regression, and quantile regression.
