ASFL: An Adaptive Model Splitting and Resource Allocation Framework for Split Federated Learning

arXiv:2603.04437v1 Announce Type: new Abstract: Federated learning (FL) enables multiple clients to collaboratively train a machine learning model without sharing their raw data. However, the limited computation resources of the clients may result in a high delay and energy consumption on training. In this paper, we propose an adaptive split federated learning (ASFL) framework over wireless networks. ASFL exploits the computation resources of the central server to train part of the model and enables adaptive model splitting as well as resource allocation during training. To optimize the learning performance (i.e., convergence rate) and efficiency (i.e., delay and energy consumption) of ASFL, we theoretically analyze the convergence rate and formulate a joint learning performance and resource allocation optimization problem. Solving this problem is challenging due to the long-term delay and energy consumption constraints as well as the coupling of the model splitting and resource alloc

arXiv:2603.04437v1 Announce Type: new Abstract: Federated learning (FL) enables multiple clients to collaboratively train a machine learning model without sharing their raw data. However, the limited computation resources of the clients may result in a high delay and energy consumption on training. In this paper, we propose an adaptive split federated learning (ASFL) framework over wireless networks. ASFL exploits the computation resources of the central server to train part of the model and enables adaptive model splitting as well as resource allocation during training. To optimize the learning performance (i.e., convergence rate) and efficiency (i.e., delay and energy consumption) of ASFL, we theoretically analyze the convergence rate and formulate a joint learning performance and resource allocation optimization problem. Solving this problem is challenging due to the long-term delay and energy consumption constraints as well as the coupling of the model splitting and resource allocation decisions. We propose an online optimization enhanced block coordinate descent (OOE-BCD) algorithm to solve the problem iteratively. Experimental results show that when compared with five baseline schemes, our proposed ASFL framework converges faster and reduces the total delay and energy consumption by up to 75% and 80%, respectively.

Executive Summary

The proposed Adaptive Split Federated Learning (ASFL) framework exhibits significant improvements in convergence rate, delay, and energy consumption compared to existing methods. By leveraging the central server's computation resources and employing adaptive model splitting and resource allocation, ASFL optimizes learning performance and efficiency. Experimental results demonstrate ASFL's superiority, achieving up to 75% reduction in total delay and 80% reduction in energy consumption. However, the framework's applicability to heterogeneous networks and scalability remain areas for further investigation. Furthermore, the impact of non-ideal network conditions, such as packet loss and latency, on ASFL's performance warrants exploration. The findings of this study have significant implications for the widespread adoption of federated learning in resource-constrained environments.

Expert Commentary

While the proposed ASFL framework demonstrates significant improvements in convergence rate, delay, and energy consumption, its practicality and scalability in real-world applications require further evaluation. Moreover, the impact of non-ideal network conditions on ASFL's performance necessitates careful consideration. Nevertheless, the findings of this study contribute significantly to the development of more efficient federated learning frameworks, with the potential to revolutionize machine learning in resource-constrained environments.
