The rapid advancement of the next generation of communications and internet of things (IoT) technologies has made the provision of location-based services for diverse devices an increasingly pressing necessity.

DePRL: Achieving Linear Convergence Speedup in Personalized Decentralized Learning with Shared Representations

no code implementations17 Dec 2023 Guojun Xiong, Gang Yan, Shiqiang Wang, Jian Li

Decentralized learning has emerged as an alternative method to the popular parameter-server framework which suffers from high communication burden, single-point failure and scalability issues due to the need of a central server.

Straggler-Resilient Decentralized Learning via Adaptive Asynchronous Updates

no code implementations11 Jun 2023 Guojun Xiong, Gang Yan, Shiqiang Wang, Jian Li

With the increasing demand for large-scale training of machine learning models, fully decentralized optimization methods have recently been advocated as alternatives to the popular parameter server framework.

Identifying Unique Causal Network from Nonstationary Time Series

1 code implementation18 Nov 2022 Mingyu Kang, Duxin Chen, Ning Meng, Gang Yan, Wenwu Yu

HCE algorithm measures the strength of causality by using nearest-neighbors entropy estimator, which works well on nonstationary time series.

Network Topology Inference based on Timing Meta-Data

no code implementations11 Oct 2022 WenBo Du, Tao Tan, Haijun Zhang, Xianbin Cao, Gang Yan, Osvaldo Simeone

If the data timings and ACK timings of two nodes -- say node 1 and node 2, respectively -- are causally related, this may be taken as evidence that node 1 is communicating to node 2 (which sends back ACK packets to node 1).

Information Prebuilt Recurrent Reconstruction Network for Video Super-Resolution

no code implementations10 Dec 2021 Shuyun Wang, Ming Yu, Cuihong Xue, Yingchun Guo, Gang Yan

By integrating sufficient information from the front of the video to build the hidden state needed for the initially recurrent unit to help restore the earlier frames, the information prebuilt network balances the input information difference at different time steps.

Critical Learning Periods in Federated Learning

no code implementations12 Sep 2021 Gang Yan, Hao Wang, Jian Li

In this work, we show that the final test accuracy of FL is dramatically affected by the early phase of the training process, i. e., FL exhibits critical learning periods, in which small gradient errors can have irrecoverable impact on the final test accuracy.

Straggler-Resilient Distributed Machine Learning with Dynamic Backup Workers

no code implementations11 Feb 2021 Guojun Xiong, Gang Yan, Rahul Singh, Jian Li

In this paradigm, each worker maintains a local estimate of the optimal parameter vector, and iteratively updates it by waiting and averaging all estimates obtained from its neighbors, and then corrects it on the basis of its local dataset.
