A Spatio-Temporal Online Robust Tensor Recovery Approach for Streaming Traffic Data Imputation
Yiyang Yang, Xiejian Chi, Shanxing Gao +2
Data quality is critical to Intelligent Transportation Systems (ITS), as complete and accurate traffic data underpin reliable decision-making in traffic control and management. Rec…
Matrix Completion with Graph Information: A Provable Nonconvex Optimization Approach
Yao Wang, Yiyang Yang, Kaidong Wang +2
We consider the problem of matrix completion with graphs as side information depicting the interrelations between variables. The key challenge lies in leveraging the similarity str…
A Unified Regularization Approach to High-Dimensional Generalized Tensor Bandits
Jiannan Li, Yiyang Yang, Yao Wang +1
Modern decision-making scenarios often involve data that is both high-dimensional and rich in higher-order contextual information, where existing bandits algorithms fail to generat…
Efficient Generalized Low-Rank Tensor Contextual Bandits
Qianxin Yi, Yiyang Yang, Shaojie Tang +2
In this paper, we aim to build a novel bandits algorithm that is capable of fully harnessing the power of multi-dimensional data and the inherent non-linearity of reward functions…
