核心内容
针对机器人视觉中旋转等变性需求与计算效率的矛盾,研究团队提出Quaternion Approximate Networks(QUAN)框架。该方法摒弃纯四元数域运算,转而利用实值操作分解哈密顿积来近似四元数卷积,并配套开发自定义CUDA内核加速。实验显示,QUAN在CIFAR-10/100及ImageNet分类任务上收敛更快、参数更少;在COCO和DOTA目标检测数据集上,其参数效率与旋转处理能力优于标准CNN,确立了四元数CNN在该下游任务的SOTA地位。
技术架构层面,QUAN引入独立四元数批归一化(IQBN)解决训练稳定性问题,并将四元数运算扩展至空间注意力机制以增强特征提取。代码已开源,验证了其在资源受限场景下的工程可行性。相比传统方法,该框架在保持几何特性的同时显著降低算力开销,为移动机器人、无人机等平台的旋转感知提供了轻量化算法基座,解决了具身智能终端在复杂姿态下目标识别精度与实时性难以兼顾的工程痛点。

英文摘要 (Abstract)
This paper introduces Quaternion Approximate Networks (QUAN), a novel deep learning framework that leverages quaternion algebra for rotation equivariant image classification and object detection. Unlike conventional quaternion neural networks attempting to operate entirely in the quaternion domain, QUAN approximates quaternion convolution through Hamilton product decomposition using real-valued operations. This approach preserves geometric properties while enabling efficient implementation with custom CUDA kernels. We introduce Independent Quaternion Batch Normalization (IQBN) for training stability and extend quaternion operations to spatial attention mechanisms. QUAN is evaluated on image classification (CIFAR-10/100, ImageNet), object detection (COCO, DOTA), and robotic perception tasks. In classification tasks, QUAN achieves higher accuracy with fewer parameters and faster convergence compared to existing convolution and quaternion-based models. For objection detection, QUAN demonstrates improved parameter efficiency and rotation handling over standard Convolutional Neural Networks (CNNs) while establishing the SOTA for quaternion CNNs in this downstream task. These results highlight its potential for deployment in resource-constrained robotic systems requiring rotation-aware perception and application in other domains.
