Deep Learning Applications in Edge Computing Systems

Deep learning at the edge involves deploying neural network models on resource-constrained devices to enable real-time analysis, reduce communication overhead and preserve data privacy. By integrating model compression techniques such as pruning, quantization and knowledge distillation with specialised hardware accelerators (GPUs, TPUs and NPUs), modern edge platforms can execute complex tasks locally. Architectures range from compact convolutional networks for vision tasks to lightweight recurrent and transformer models for time-series and natural language data. Key applications include autonomous vehicle perception, smart surveillance, industrial quality inspection, precision agriculture and wearable health monitoring. These deployments deliver low-latency inference, adapt to variable connectivity and lower the environmental footprint of centralized data centres. Growth in end-to-end toolchains and software frameworks has enhanced portability across single-board computers, embedded GPUs and custom ASICs. Despite advances, challenges remain in balancing inference speed, energy consumption and model accuracy under tight memory and compute budgets. Emerging solutions focus on co-designing algorithms and hardware, dynamic workload scheduling and federated learning at the edge to further unlock the potential of distributed intelligence in global IoT ecosystems.

Recent reviews of GPU-accelerated single-board computers survey both hardware architectures and software toolchains for computer vision at the edge. They document advances in algorithm-level optimisation, compiler support and deployment frameworks that allow complex convolutional and transformer-based models to run efficiently on devices such as NVIDIA Jetson and Google Coral. Quantitative benchmarks of object detection networks compare variants of YOLO on platforms including Jetson Nano, Jetson AGX Xavier and Coral Dev Board, highlighting trade-offs among detection accuracy, inference latency, energy efficiency and cost. These studies provide practical guidelines for selecting device-model combinations in different application scenarios. Another line of work proposes parallel multi-frame processing schemes on multi-core IoT edge devices, partitioning video streams to cores for concurrent YOLO inference. Such designs achieve up to fourfold improvements in throughput, significant reductions in power use and lower memory overhead, demonstrating the benefits of algorithm–hardware co-design and dynamic scheduling in real-world deployments.
