Socialized Detector Learning: Trajectory-Guided and Reciprocal Distillation for Heterogeneous Object Detectors

Read the original on arXiv Computer Vision →

The paper introduces Socialized Detector Learning (SDL), a framework for improving heterogeneous, category-specialized object detectors by exchanging knowledge within a detector society. It proposes Trajectory-Guided and Reciprocal Distillation (TGRD), which estimates transfer difficulty, constructs a carrier trajectory, and performs progressive consolidation and reciprocal transfer. Experiments on MS COCO show that carriers outperform simultaneous aggregation by 2.6 AP, and reciprocal detectors achieve high AP on previously unsupported categories while staying close to expert performance.

CSCWD: Cross-Scale Channel-wise Knowledge Distillation for Lightweight Tiny Object Detection on Edge Devices

The paper introduces Cross-Scale Channel-wise Knowledge Distillation (CSCWD), a training-time framework that transfers high‑resolution spatial representations from a YOLO11m‑P2 teacher to a lightweight YOLO11n student without changing the student’s inference architecture. CSCWD aligns teacher P2 features with student P3 while also applying same‑scale distillation at deeper pyramid levels, yielding a 2.92‑point mAP@0.5 improvement over the baseline and a 2.09‑point gain over same‑scale distillation alone. In zero‑shot tests on DUT‑Anti‑UAV and on a Raspberry Pi 5, the 2.58‑million‑parameter student reaches 50.32% mAP@0.5 at 82.32 ms latency (12.15 fps) with negligible runtime or memory increase.

Rethinking Classifier-Free Guidance in On-Policy Diffusion Distillation

arXiv:2607. 24731v1 Announce Type: cross Abstract: On-policy distillation (OPD) adapts diffusion models by querying a teacher along trajectories generated by the current student, but how it should behave under classifier-free guidance (CFG), a default component of modern diffusion systems, remains poorly understood.

Socialized UAV Cross-Task Learning: Towards Cross-Granularity Collaboration through Hierarchical Interaction

The paper introduces CrossUAV, a benchmark for joint object detection and instance segmentation in UAV imagery, and proposes Cross-Granularity Socialized Collaboration (CGSC), a framework that regulates hierarchical interactions between tasks. CGSC progressively activates cross-task exchanges and adaptively adjusts interaction strength based on task contribution, aiming to reduce interference and exploit complementary coarse- and fine-grained knowledge. Experiments show consistent improvements on both detection and segmentation tasks, supporting the effectiveness of hierarchical dynamic interaction for cross-granularity collaboration.
