Leveraging Untrustworthy Commands for Multi-Robot Coordination in Unpredictable Environments: A Bandit Submodular Maximization Approach
Zirui Xu, Xiaofeng Lin, Vasileios Tzoumas
We study the problem of multi-agent coordination in unpredictable and partially-observable environments with untrustworthy external commands. The commands are actions suggested to…
Bandit Submodular Maximization for Multi-Robot Coordination in Unpredictable and Partially Observable Environments
Zirui Xu, Xiaofeng Lin, Vasileios Tzoumas
We study the problem of multi-agent coordination in unpredictable and partially observable environments, that is, environments whose future evolution is unknown a priori and that c…
DensE: An Enhanced Non-commutative Representation for Knowledge Graph Embedding with Adaptive Semantic Hierarchy
Haonan Lu, Hailin Hu, Xiaodong Lin
Capturing the composition patterns of relations is a vital task in knowledge graph completion. It also serves as a fundamental step towards multi-hop reasoning over learned knowled…
Selective Linearization For Multi-Block Convex Optimization
Yu Du, Xiaodong Lin, Andrzej Ruszczynski
We consider the problem of minimizing a sum of several convex non-smooth functions. We introduce a new algorithm called the selective linearization method, which iteratively linear…
Multi-way blockmodels for analyzing coordinated high-dimensional responses
Edoardo M. Airoldi, Xiaopei Wang, Xiaodong Lin
We consider the problem of quantifying temporal coordination between multiple high-dimensional responses. We introduce a family of multi-way stochastic blockmodels suited for this…
Alternating Linearization for Structured Regularization Problems
Xiaodong Lin, Minh Pham, Andrzej Ruszczynski
We adapt the alternating linearization method for proximal decomposition to structured regularization problems, in particular, to the generalized lasso problems. The method is rela…
