How Robust is Federated Learning to Communication Error? A Comparison Study Between Uplink and Downlink Channels

no code implementations25 Oct 2023 Linping Qu, Shenghui Song, Chi-Ying Tsui, Yuyi Mao

It is also shown that the uplink communication in FL can tolerate a higher bit error rate (BER) than downlink communication, and this difference is quantified by a proposed formula.

Step-GRAND: A Low Latency Universal Soft-input Decoder

no code implementations14 Jul 2023 Syed Mohsin Abbas, Marwan Jalaleddine, Chi-Ying Tsui, Warren J. Gross

GRAND features both soft-input and hard-input variants that are well suited to efficient hardware implementations that can be characterized with achievable average and worst-case decoding latency.

FedDQ: Communication-Efficient Federated Learning with Descending Quantization

no code implementations5 Oct 2021 Linping Qu, Shenghui Song, Chi-Ying Tsui

Experimental results show that the proposed descending quantization scheme can save up to 65. 2% of the communicated bit volume and up to 68% of the communication rounds, when compared with existing schemes.

Accelerating Large Kernel Convolutions with Nested Winograd Transformation.pdf

no code implementations26 Feb 2021 Jingbo Jiang, Xizi Chen, Chi-Ying Tsui

This work proposes a nested Winograd algorithm that iteratively decomposes a large kernel convolution into small kernel convolutions and proves it to be more effective than the linear decomposition Winograd transformation algorithm.
