Communication-Efficient Local SGD with Age-Based Worker Selection
Feng Zhu, Jingjing Zhang, Xin Wang
A major bottleneck of distributed learning under parameter-server (PS) framework is communication cost due to frequent bidirectional transmissions between the PS and workers. To ad…
Adaptive Worker Grouping For Communication-Efficient and Straggler-Tolerant Distributed SGD
Feng Zhu, Jingjing Zhang, Osvaldo Simeone +1
Wall-clock convergence time and communication load are key performance metrics for the distributed implementation of stochastic gradient descent (SGD) in parameter server settings.…
Coded Alternating Least Squares for Straggler Mitigation in Distributed Recommendations
Siyuan Wang, Qifa Yan, Jingjing Zhang +2
Matrix factorization is an important representation learning algorithm, e.g., recommender systems, where a large matrix can be factorized into the product of two low dimensional ma…
Coded Computing and Cooperative Transmission for Wireless Distributed Matrix Multiplication
Kuikui Li, Meixia Tao, Jingjing Zhang +1
Consider a multi-cell mobile edge computing network, in which each user wishes to compute the product of a user-generated data matrix with a network-stored matrix. This is done thr…
ITENE: Intrinsic Transfer Entropy Neural Estimator
Jingjing Zhang, Osvaldo Simeone, Zoran Cvetkovic +2
Quantifying the directionality of information flow is instrumental in understanding, and possibly controlling, the operation of many complex systems, such as transportation, social…
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…
Wireless Map-Reduce Distributed Computing with Full-Duplex Radios and Imperfect CSI
Sukjong Ha, Jingjing Zhang, Osvaldo Simeone +1
Consider a distributed computing system in which the worker nodes are connected over a shared wireless channel. Nodes can store a fraction of the data set over which computation ne…
Improved Latency-Communication Trade-Off for Map-Shuffle-Reduce Systems with Stragglers
Jingjing Zhang, Osvaldo Simeone
In a distributed computing system operating according to the map-shuffle-reduce framework, coding data prior to storage can be useful both to reduce the latency caused by stragglin…
