🔄 Framework Overview

---

🔧 Getting Started

▶️ To apply the framework:

1. Run data.py to prepare the dataset.
2. Then sequentially execute the following scripts:
   • c1_code/c1_train.py
   • c1_code/c1_main.py
   • c3_code/c2_main.py
   • c3_code/c3_main.py
   • c3_code/c3_final_embeddings.py

These steps will preprocess the data, train the model, and generate the final embeddings.

🧠 To check Grad-CAM results:

After you got save models in c1, c3 and correctly configured path, run:

python Grad_CAM_main.py
