Temporal-Spatial Object Relations Modeling for Vision-and-Language Navigation

no code implementations23 Mar 2024 Bowen Huang, Yanwei Zheng, Chuanlin Lan, Xinpeng Zhao, Dongxiao Yu, Yifei Zou

To avoid this problem, we construct object connections based on observations from all viewpoints in the navigational environment, which ensures complete spatial coverage and eliminates the gap, called Spatial Object Relations (SOR).

Communication Efficient and Provable Federated Unlearning

no code implementations19 Jan 2024 Youming Tao, Cheng-Long Wang, Miao Pan, Dongxiao Yu, Xiuzhen Cheng, Di Wang

We start by giving a rigorous definition of \textit{exact} federated unlearning, which guarantees that the unlearned model is statistically indistinguishable from the one trained without the deleted data.

CPCL: Cross-Modal Prototypical Contrastive Learning for Weakly Supervised Text-based Person Re-Identification

1 code implementation18 Jan 2024 Yanwei Zheng, Xinpeng Zhao, Chuanlin Lan, Xiaowei Zhang, Bowen Huang, Jibin Yang, Dongxiao Yu

Weakly supervised text-based person re-identification (TPRe-ID) seeks to retrieve images of a target person using textual descriptions, without relying on identity annotations and is more challenging and practical.

Resource-Adaptive Newton's Method for Distributed Learning

no code implementations20 Aug 2023 Shuzhen Chen, Yuan Yuan, Youming Tao, Zhipeng Cai, Dongxiao Yu

Distributed stochastic optimization methods based on Newton's method offer significant advantages over first-order methods by leveraging curvature information for improved performance.

Byzantine-Resilient Federated Learning at Edge

no code implementations18 Mar 2023 Youming Tao, Sijia Cui, Wenlu Xu, Haofei Yin, Dongxiao Yu, Weifa Liang, Xiuzhen Cheng

To address this issue, we study the stochastic convex and non-convex optimization problem for federated learning at edge and show how to handle heavy-tailed data while retaining the Byzantine resilience, communication efficiency and the optimal statistical error rates simultaneously.
