We offer a position at a leading technical university that generates knowledge and skills for a sustainable future. You will have engaged and ambitious colleagues along with a creative, international and dynamic working environment. You will work in Gothenburg but with the close collaboration with the research team at Ericsson in Stockholm.
Information about the project and the research
The purpose of the project is to develop a scalable distributed machine learning paradigm, where multiple threads are introduced in federated learning (FL), referred to as multi-thread federated learning (MFL), to boost learning accuracy and efficiency. However, the long convergence time, caused by model update/aggregation between the FL clients and the central server, prevents the FL from being implemented for many emerging low-latency services, e.g., autonomous driving.
The following activities will be performed in the frame of the project:
1. Multi-thread protocol design, where multiple threads are introduced in the training process. Each training round is composed of three elements, namely local training, model exchange, and model aggregation/update. The principle of the MFL is to interleave various elements in different training rounds, fully utilizing the local computation power to speed up the training process. In this activity, a communication protocol tailored for the MFL will be designed. New model aggregate/update functions will also be investigated, which allows the central server to coordinate the different threads and fully explore the benefits of the MFL. Moreover, other key aspects will be investigated, incl. robustness, scalability and energy efficiency.
2. Queueing model will be derived to analyze the training time and gain a fundamental understanding of the convergence time for the FL. In the cases where the analytical model will be too complex, the discrete event driven simulator will be developed to bound the delay performance for the general traffic patterns.
3. Use case specification and validation will be carried out through tight collaborations with Ericsson. Use cases that are highly aligned with Ericsson's solutions for 5G and beyond will be prioritized. Given a specified use case, the performance of the designed MFL will be validated.
Major responsibilities
Design of an appropriate multi-thread protocol. Deriving and validating of the related queuing models.
