Federated Learning for Computationally-Constrained Heterogeneous Devices: A Survey

no code implementations18 Jul 2023 Kilian Pfeiffer, Martin Rapp, Ramin Khalili, Jörg Henkel

With an increasing number of smart devices like internet of things (IoT) devices deployed in the field, offloadingtraining of neural networks (NNs) to a central server becomes more and more infeasible.

Multi-Agent Reinforcement Learning for Long-Term Network Resource Allocation through Auction: a V2X Application

no code implementations29 Jul 2022 Jing Tan, Ramin Khalili, Holger Karl, Artur Hecker

We formulate offloading of computational tasks from a dynamic group of mobile agents (e. g., cars) as decentralized decision making among autonomous agents.

Scheduling Out-of-Coverage Vehicular Communications Using Reinforcement Learning

no code implementations13 Jul 2022 Taylan Şahin, Ramin Khalili, Mate Boban, Adam Wolisz

To exploit the benefits of the centralized approach for enhancing the reliability of V2V communications on roads lacking cellular coverage, we propose VRLS (Vehicular Reinforcement Learning Scheduler), a centralized scheduler that proactively assigns resources for out-of-coverage V2V communications \textit{before} vehicles leave the cellular network coverage.

Learning to Bid Long-Term: Multi-Agent Reinforcement Learning with Long-Term and Sparse Reward in Repeated Auction Games

1 code implementation5 Apr 2022 Jing Tan, Ramin Khalili, Holger Karl

We propose a multi-agent distributed reinforcement learning algorithm that balances between potentially conflicting short-term reward and sparse, delayed long-term reward, and learns with partial information in a dynamic environment.

CoCoFL: Communication- and Computation-Aware Federated Learning via Partial NN Freezing and Quantization

1 code implementation10 Mar 2022 Kilian Pfeiffer, Martin Rapp, Ramin Khalili, Jörg Henkel

To adapt to the devices' heterogeneous resources, CoCoFL freezes and quantizes selected layers, reducing communication, computation, and memory requirements, whereas other layers are still trained in full precision, enabling to reach a high accuracy.

VRLS: A Unified Reinforcement Learning Scheduler for Vehicle-to-Vehicle Communications

no code implementations22 Jul 2019 Taylan Şahin, Ramin Khalili, Mate Boban, Adam Wolisz

VRLS is a unified reinforcement learning (RL) solution, wherein the learning agent, the state representation, and the reward provided to the agent are applicable to different vehicular environments of interest (in terms of vehicular density, resource configuration, and wireless channel conditions).

Reinforcement Learning Scheduler for Vehicle-to-Vehicle Communications Outside Coverage

no code implementations29 Apr 2019 Taylan Şahin, Ramin Khalili, Mate Boban, Adam Wolisz

Radio resources in vehicle-to-vehicle (V2V) communication can be scheduled either by a centralized scheduler residing in the network (e. g., a base station in case of cellular systems) or a distributed scheduler, where the resources are autonomously selected by the vehicles.
