English(EN) Information Density Imbalance in Visual Object Detection

新的“信息密度”指标解决了视觉对象检测中的偏差问题

作者 PulseAugur 编辑部 · [1 个来源] · 2026-09-03 04:00

研究人员引入了一个名为“信息密度”的新概念来解释视觉对象检测模型中的类别偏差，超越了传统的实例数量关注点。他们观察到类别的“信息密度”与其准确率之间存在负相关，这表明信息密度不平衡（而不仅仅是实例数量）会导致模型偏差。通过将信息密度纳入对象检测损失函数，在 PASCAL VOC、COCO-LT 和 LVIS 数据集上的实验显示，模型偏差有所减少，整体性能有所提高。 AI

影响引入了一个新指标，有望提高视觉对象检测模型的公平性和性能。

视觉目标检测中的信息密度不平衡

arXiv:2609.02369v1 Announce Type: new Abstract: In object detection, the number of instances is typically used to determine whether a dataset exhibits a long-tailed distribution, implicitly assuming that the model will perform poorly on categories with fewer instances. This assum…
