+ # Grounded Teacher (GT)
19
+
20
+ This repository contains model weights and resources for **Grounded Teacher**, a framework designed to tackle **Source Free Object Detection (SFOD)**, especially under **domain shift** and **context imbalance** conditions—common challenges in **medical imaging**.

+ ## 🧠 Abstract
25
+
26
+ We focus on the Source Free Object Detection (SFOD) problem, where **source data is unavailable** during adaptation, and the model must adapt to an **unlabeled target domain**. In medical imaging, many approaches rely on semi-supervised student-teacher setups to handle domain gaps.
27
+
28
+ However, **context imbalance** and **domain shifts** often lead to **biased teacher models**, producing poor pseudolabels and causing the student model to collapse.
29
+
30
+ To address this, we introduce **Grounded Teacher (GT)**:
31
+ - Models **contextual relationships** via a **relational context module**.
32
+ - Applies targeted **augmentations** for underrepresented classes across/within domains.
33
+ - Adds an **expert foundational branch** to supervise the student model and enhance prediction quality.
34
+
35
+ GT shows significant improvement across three medical imaging datasets, with thorough ablation studies validating its effectiveness.
