FeDeRA:Efficient Fine-tuning of Language Models in Federated Learning Leveraging Weight Decomposition

no code implementations29 Apr 2024 Yuxuan Yan, Shunpu Tang, Zhiguo Shi, Qianqian Yang

However, we observe that the non-IID data in federated learning leads to a gap in performance between the PEFT method and full parameter fine-tuning(FFT).

Augmented Labeled Random Finite Sets and Its Application to Group Target Tracking

no code implementations20 Mar 2024 Chaoqun Yang, Mengdie Xu, Xiaowei Liang, Zhiguo Shi, Heng Zhang, Xianghui Cao

Furthermore, by means of the labeled multi-Bernoulli (LMB) filter with the proposed augmented LRFSs, the group structure is iteratively propagated and updated during the tracking process, which achieves the simultaneously estimation of the kinetic states, track label, and the corresponding group information of multiple group targets, and further improves the GTT tracking performance.

AsyncFedED: Asynchronous Federated Learning with Euclidean Distance based Adaptive Weight Aggregation

1 code implementation27 May 2022 Qiyuan Wang, Qianqian Yang, Shibo He, Zhiguo Shi, Jiming Chen

In an asynchronous federated learning framework, the server updates the global model once it receives an update from a client instead of waiting for all the updates to arrive as in the synchronous setting.

Global and Asymptotically Efficient Localization from Range Measurements

no code implementations31 Mar 2022 Guangyang Zeng, Biqiang Mu, Jiming Chen, Zhiguo Shi, Junfeng Wu

In terms of whether the variance of measurement noises is known or not, we propose the Bias-Eli estimator (which involves solving a generalized trust region subproblem) and the Noise-Est estimator (which is obtained by solving a convex problem), respectively.
