Adaptive Client Selection with Personalization for Communication Efficient Federated Learning
This addresses communication efficiency for federated learning systems, particularly in scenarios with non-IID data, though it appears incremental as it builds on existing client selection and personalization techniques.
The paper tackles communication bottlenecks in federated learning by introducing ACSP-FL, a method that adaptively selects clients and personalizes models, reducing communication by up to 95% compared to existing approaches while maintaining convergence.
Federated Learning (FL) is a distributed approach to collaboratively training machine learning models. FL requires a high level of communication between the devices and a central server, thus imposing several challenges, including communication bottlenecks and network scalability. This article introduces ACSP-FL (https://github.com/AllanMSouza/ACSP-FL), a solution to reduce the overall communication and computation costs for training a model in FL environments. ACSP-FL employs a client selection strategy that dynamically adapts the number of devices training the model and the number of rounds required to achieve convergence. Moreover, ACSP-FL enables model personalization to improve clients performance. A use case based on human activity recognition datasets aims to show the impact and benefits of ACSP-FL when compared to state-of-the-art approaches. Experimental evaluations show that ACSP-FL minimizes the overall communication and computation overheads to train a model and converges the system efficiently. In particular, ACSP-FL reduces communication up to 95% compared to literature approaches while providing good convergence even in scenarios where data is distributed differently, non-independent and identical way between client devices.
