Online Generalized Sparse Regression: How Does Overparametrization Help?
Shuoguang Yang, Qiang Sun
Regularized sparse regression has been extensively studied in the offline setting, but online formulation remains relatively under-explored. This gap stems from four key challenges…
Online Linearized LASSO
Shuoguang Yang, Yuhao Yan, Xiuneng Zhu +1
Sparse regression has been a popular approach to perform variable selection and enhance the prediction accuracy and interpretability of the resulting statistical model. Existing ap…
Decentralized Gossip-Based Stochastic Bilevel Optimization over Communication Networks
Shuoguang Yang, Xuezhou Zhang, Mengdi Wang
Bilevel optimization have gained growing interests, with numerous applications found in meta learning, minimax games, reinforcement learning, and nested composition optimization. T…
Information-Directed Selection for Top-Two Algorithms
Wei You, Chao Qin, Zihao Wang +1
We consider the best-k-arm identification problem for multi-armed bandits, where the objective is to select the exact set of k arms with the highest mean rewards by sequentially al…
