Federated Double Deep Q-learning for Joint Delay and Energy Minimization in IoT networks
Bibliographic record
Abstract
In this paper, we propose a federated deep reinforcement learning framework to solve a multi-objective optimization problem, where we consider minimizing the expected long-term task completion delay and energy consumption of IoT devices. This is done by optimizing offloading decisions, computation resource allocation, and transmit power allocation. Since the formulated problem is a mixed-integer non-linear programming (MINLP), we first cast our problem as a multi-agent distributed deep reinforcement learning (DRL) problem and address it using double deep Q-network (DDQN), where the actions are offloading decisions. The immediate cost of each agent is calculated through solving either the transmit power optimization or local computation resource optimization, based on the selected offloading decisions (actions). Then, to enhance the learning speed of IoT devices (agents), we incorporate federated learning (FDL) at the end of each episode. FDL enhances the scalability of the proposed DRL framework, creates a context for cooperation between agents, and minimizes their privacy concerns. Our numerical results demonstrate the efficacy of our proposed federated DDQN framework in terms of learning speed compared to federated deep Q network (DQN) and non-federated DDQN algorithms. In addition, we investigate the impact of batch size, network layers, DDQN target network update frequency on the learning speed of the FDL.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
