Leveraging Untrustworthy Commands for Multi-Robot Coordination in Unpredictable Environments: A Bandit Submodular Maximization Approach

no code implementations28 Sep 2023 Zirui Xu, Xiaofeng Lin, Vasileios Tzoumas

MetaBSG leverages a meta-algorithm to learn whether the robots should follow the commands or a recently developed submodular coordination algorithm, Bandit Sequential Greedy (BSG) [1], which has performance guarantees even in unpredictable and partially-observable environments.

Estimating Treatment Effects Under Heterogeneous Interference

1 code implementation25 Sep 2023 Xiaofeng Lin, Guoxi Zhang, Xiaotian Lu, Han Bao, Koh Takeuchi, Hisashi Kashima

One popular application of this estimation lies in the prediction of the impact of a treatment (e. g., a promotion) on an outcome (e. g., sales) of a particular unit (e. g., an item), known as the individual treatment effect (ITE).

Bandit Submodular Maximization for Multi-Robot Coordination in Unpredictable and Partially Observable Environments

1 code implementation22 May 2023 Zirui Xu, Xiaofeng Lin, Vasileios Tzoumas

We are motivated by the future of autonomy that involves multiple robots coordinating actions in dynamic, unstructured, and partially observable environments to complete complex tasks such as target tracking, environmental mapping, and area monitoring.

FairGRAPE: Fairness-aware GRAdient Pruning mEthod for Face Attribute Classification

1 code implementation22 Jul 2022 Xiaofeng Lin, Seungbae Kim, Jungseock Joo

Existing pruning techniques preserve deep neural networks' overall ability to make correct predictions but may also amplify hidden biases during the compression process.
