Abstract
Achieving ultra-reliable real-time digital twin (DT) adaptation in mobile edge environments requires intelligent orchestration of computation and communication under user heterogeneity and dynamic mobility. This paper introduces GADENet, a graph attention-enhanced digital twin evolution network that fuses graph neural modelling, multi-agent actor-critic learning, and hierarchical federated personalisation to enable seamless digital representations of user equipment (UE) in distributed edge networks. At its core, GADENet employs a GAT-assisted multi-agent deep deterministic policy gradient (MADDPG) framework to jointly learn optimal DT migration and personalisation strategies across edge servers, guided by real-time traffic topologies and resource interdependencies. Each DT model is modularised into generalisable and adaptive subspaces, trained collaboratively through a three-tier edge-cloud federated loop and refined using localised attention-based updates. For efficient mobility handling, we propose a parameter-sliced DT relay protocol that selectively migrates the minimal personalisation subset across servers, leveraging learned action-value functions to minimise response latency. Extensive simulations on CIFAR-based datasets and synthetic edge workloads demonstrate that GADENet achieves up to 30% reduction in interaction latency and significantly boosts modelling fidelity versus strong federated and DRL-based baselines. This work offers a principled blueprint for intelligent DT deployment under the constraints of 6G and next-gen IoT fabrics.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
