# Grounded Teacher (GT) |
|
|
|
|
|
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 |
|
|
|
|
|
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. |
|
|
|
|
|
However, **context imbalance** and **domain shifts** often lead to **biased teacher models**, producing poor pseudolabels and causing the student model to collapse. |
|
|
|
|
|
To address this, we introduce **Grounded Teacher (GT)**: |
|
|
- Models **contextual relationships** via a **relational context module**. |
|
|
- Applies targeted **augmentations** for underrepresented classes across/within domains. |
|
|
- Adds an **expert foundational branch** to supervise the student model and enhance prediction quality. |
|
|
|
|
|
GT shows significant improvement across three medical imaging datasets, with thorough ablation studies validating its effectiveness. |
