针对小图分类优化模型架构,提升边缘设备推理效率

GhostNetV3-Small: A Tailored Architecture and Comparative Study of Distillation Strategies for Tiny Images

  • 设计轻量版GhostNetV3-Small,适配低分辨率输入
  • 在CIFAR-10上达93.94%准确率,优于原模型
  • 发现蒸馏策略反降低性能,架构改进更关键

深度神经网络在各类任务中表现优异,但计算开销大,难以部署于资源受限的边缘设备。本文研究模型压缩与适配策略,以实现高效推理。聚焦移动端前沿架构GhostNetV3,提出改进版GhostNetV3-Small,专为低分辨率图像(如CIFAR-10)设计。除架构调整外,还对比了传统蒸馏、教师助手与教师集成等知识蒸馏方法。实验表明,GhostNetV3-Small在CIFAR-10上准确率达93.94%,显著优于原模型。出乎意料的是,所有蒸馏策略均导致准确率下降。结果说明,在小图分类任务中,架构优化比蒸馏更有效,凸显低分辨率场景下模型设计与先进蒸馏技术研究的重要性。

原文摘要 · Abstract (English)

Deep neural networks have achieved remarkable success across a range of tasks, however their computational demands often make them unsuitable for deployment on resource-constrained edge devices. This paper explores strategies for compressing and adapting models to enable efficient inference in such environments. We focus on GhostNetV3, a state-of-the-art architecture for mobile applications, and propose GhostNetV3-Small, a modified variant designed to perform better on low-resolution inputs such as those in the CIFAR-10 dataset. In addition to architectural adaptation, we provide a comparative evaluation of knowledge distillation techniques, including traditional knowledge distillation, teacher assistants, and teacher ensembles. Experimental results show that GhostNetV3-Small significantly outperforms the original GhostNetV3 on CIFAR-10, achieving an accuracy of 93.94%. Contrary to expectations, all examined distillation strategies led to reduced accuracy compared to baseline training. These findings indicate that architectural adaptation can be more impactful than distillation in small-scale image classification tasks, highlighting the need for further research on effective model design and advanced distillation techniques for low-resolution domains.
