An Efficient Piggybacking Design Framework with Sub-packetization $lle r$ for All-Node Repair

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Zhifang Zhang, , , | Summary: Piggybacking design has been widely applied in distributed storage systems since it can greatly reduce the repair bandwidth with small sub-packetization. Compared with other existing erasure codes, piggybacking is more convenient to operate and the I/O cost is lower. […]

CHARLES: Channel-Quality-Adaptive Over-the-Air Federated Learning over Wireless Networks

Kavli Affiliate: Jia Liu | First 5 Authors: Jiayu Mao, Haibo Yang, Peiwen Qiu, Jia Liu, Aylin Yener | Summary: Over-the-air federated learning (OTA-FL) has emerged as an efficient mechanism that exploits the superposition property of the wireless medium and performs model aggregation for federated learning in the air. OTA-FL is naturally sensitive to wireless […]
