LAMBO: Large AI Model Empowered Edge Intelligence
This work addresses edge intelligence offloading problems for applications in next-generation networks, but it appears incremental as it builds on existing transformer and reinforcement learning methods.
The paper tackles the challenges of traditional edge intelligence offloading, such as heterogeneous constraints and uncertain generalization, by proposing the LAMBO framework with over one billion parameters, which achieves improved performance in simulations.
Next-generation edge intelligence is anticipated to benefit various applications via offloading techniques. However, traditional offloading architectures face several issues, including heterogeneous constraints, partial perception, uncertain generalization, and lack of tractability. In this paper, we propose a Large AI Model-Based Offloading (LAMBO) framework with over one billion parameters for solving these problems. We first use input embedding (IE) to achieve normalized feature representation with heterogeneous constraints and task prompts. Then, we introduce a novel asymmetric encoder-decoder (AED) as the decision-making model, which is an improved transformer architecture consisting of a deep encoder and a shallow decoder for global perception and decision. Next, actor-critic learning (ACL) is used to pre-train the AED for different optimization tasks under corresponding prompts, enhancing the AED's generalization in multi-task scenarios. Finally, we propose an active learning from expert feedback (ALEF) method to fine-tune the decoder of the AED for tracking changes in dynamic environments. Our simulation results validate the advantages of the proposed LAMBO framework.
