Design and Optimization of Heterogeneous Coded Distributed Computing with Nonuniform File Popularity

2023 · arXiv (Cornell University)

This paper studies MapReduce-based heterogeneous coded distributed computing (CDC) where, besides different computing capabilities at workers, input files to be accessed by computing jobs have nonuniform popularity. We propose a file placement strategy that can …

Uplink Over-the-Air Aggregation for Multi-Model Wireless Federated Learning

2024

We propose an uplink over-the-air aggregation (OAA) method for wireless federated learning (FL) that simultaneously trains multiple models. To maximize the multi-model training convergence rate, we derive an upper bound on the optimality gap of …
