Context Aware Grounded Teacher for Source Free Object Detection 事件

Context Aware Grounded Teacher for Source Free Object Detection arXiv:2504.15404v3 Announce Type: replace Abstract: Source-free object detection (SFOD) faces persistent challenges due to class imbalance-driven context bias and instability in teacher-student training under noisy pseudo-labels. Existing techniques tend to ignore context bias and class-imbalance shifts, especially in medical data. To tackle this, we propose Grounded Teacher (GT), a bias-aware source-free framework that grounds the
