📝 摘要(中文)

目标检测知识在独立训练的异构检测器之间是碎片化的,这些检测器支持互补的类别。社会化学习旨在通过知识交换集体进化这些检测器,但现有的聚合方法未能明确规划知识转移顺序。本文提出社会化检测器学习(SDL)和基于轨迹引导的互惠蒸馏(TGRD),通过估计检测器间转移难度并构建知识转移轨迹,实现知识的逐步整合与回馈。实验表明,最终的知识载体在MS COCO数据集上相较于传统方法提升了2.6 AP,并在未支持类别上达到了20.8-28.4 AP的性能。

📄 摘要(原文)

Object detection knowledge is fragmented across independently trained, heterogeneous detectors with complementary category supports. In socialized learning, this knowledge resides in a society, and learning aims to evolve the society collectively through exchange. However, aggregation-based socialization does not explicitly plan transfer order, whereas progressive multi-teacher distillation considers order but remains a one-way student enhancement in a shared category space. Building on Socialized Learning, we formulate Socialized Detector Learning (SDL) for heterogeneous, category-specialized object detectors and propose Trajectory-Guided and Reciprocal Distillation (TGRD).TGRD estimates directed operational Inter-Detector Transfer Difficulty (IDTD) from held-out feature-alignment residuals, precomputes a fixed score table, and greedily constructs a carrier trajectory. Along the trajectory, knowledge is progressively consolidated into a union-category carrier and then returned to experts through reciprocal transfer. A conditional proxy-certificate analysis shows that, under stated assumptions, the progressive certificate is no larger than an aggregated-target counterpart. On MS COCO with four heterogeneous experts and two carrier initializations, final carriers outperform epoch-matched simultaneous aggregation controls by 2.6 AP in both settings. Reciprocal detectors attain 20.8--28.4 AP on previously unsupported categories while remaining within 1.3 AP of original expert-specific performance. These results support order-aware progressive consolidation followed by reciprocal transfer as a viable mechanism for detector-society evolution.
