Fundamental Limits of Wireless Caching under Uneven-Capacity Channels
Eleftherios Lampiris, Jingjing Zhang, Osvaldo Simeone +1
This work identifies the fundamental limits of cache-aided coded multicasting in the presence of the well-known `worst-user' bottleneck. This stems from the presence of receiving u…
LAGC: Lazily Aggregated Gradient Coding for Straggler-Tolerant and Communication-Efficient Distributed Learning
Jingjing Zhang, Osvaldo Simeone
Gradient-based distributed learning in Parameter Server (PS) computing architectures is subject to random delays due to straggling worker nodes, as well as to possible communicatio…
On Model Coding for Distributed Inference and Transmission in Mobile Edge Computing Systems
Jingjing Zhang, Osvaldo Simeone
Consider a mobile edge computing system in which users wish to obtain the result of a linear inference operation on locally measured input data. Unlike the offloaded input data, th…
Cloud-Aided Interference Management with Cache-Enabled Edge Nodes and Users
Seyed Pooya Shariatpanahi, Jingjing Zhang, Osvaldo Simeone +2
This paper considers a cloud-RAN architecture with cache-enabled multi-antenna Edge Nodes (ENs) that deliver content to cache-enabled end-users. The ENs are connected to a central…
Coded Federated Computing in Wireless Networks with Straggling Devices and Imperfect CSI
Sukjong Ha, Jingjing Zhang, Osvaldo Simeone +1
Distributed computing platforms typically assume the availability of reliable and dedicated connections among the processors. This work considers an alternative scenario, relevant…
