Abstract

fetched live from OpenAlex

Collaboration among mobile edge computing (MEC) has been envisioned as a promising paradigm to meet the requirements of wireless virtual reality (VR) applications. However, trust risks create tremendous challenges in MEC collaboration due to the distributed, complex, and unreliable nature of resource providers. In this paper, we present a trusted collaboration framework for VR video streaming to manage the video buffer in VR devices (VDs) under a more realistic distributed environment. In the framework, the rendering tasks can be processed collaboratively among edge servers (ESs) by exploring their behaviors (e.g., selfish behavior, malicious behavior, and cooperative behavior). Considering the collaborator may not be fully trustworthy, we present a novel trust evaluation method by combining direct and indirect values, aiming to ensure reliable collaborator selection. Then, we formulate an optimization problem to maintain an effective buffer state in VR devices (VDs) through jointly optimizing collaborator selection, spectrum allocation, and rendering resource allocation. Due to the fluctuating wireless fading channel and the dynamic video rate, the optimization problem is intractable by adopting traditional methods. Then, we adopt the multi-agent deep deterministic policy gradient (MADDPG) to tackle this dynamic and distributed problem. Simulation results indicate that the proposed approach can achieve a good performance.

Full frame distilled prediction

Teacher imitation

Not 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.
