EdgeVision introduces a Multiagent Reinforcement Learning (MARL) framework, enhanced with an attention mechanism, enabling distributed edge nodes to collaboratively optimize video preprocessing, DNN model selection, and inference request dispatching for real-time video analytics. This system delivers a 33.6% to 86.4% performance improvement and a 92.8% reduction in video frame drop rates compared to baseline methods.
Key insights
- Collaborative decision-making among distributed edge nodes, facilitated by MARL, offers significantly enhanced performance over independent or static resource management strategies.
- An attention mechanism within the MARL critic network is critical for effectively processing global state information, improving the efficiency and accuracy of policy learning in multi-agent systems.
- The system dynamically adapts video preprocessing (resolution), DNN model selection, and request dispatching based on workload and performance priorities, intelligently balancing accuracy and delay.
