 By addressing these challenges during preprocessing and model design, performance on challenging classes and smaller abnormalities can be significantly improved.
 
+## Baseline Adjustments and Improvements
+
+### Enhanced Class Handling:
+- **Weighted Loss**: Improved model performance by addressing class imbalance through weighted loss adjustments.
+- **Streamlined Data Augmentation**: Applied advanced augmentation techniques to improve model generalization and robustness.
+
+### Augmentation Techniques Applied:
+1. **Random Horizontal Flip**: Simulates flipped X-ray orientations to improve model robustness.
+2. **Random Rotation**: Introduces minor rotational variance (±10 degrees) to mimic natural misalignments.
+3. **Color Jitter**: Adjusts brightness and contrast to replicate real-world lighting inconsistencies.
+4. **Normalization**: Scales pixel values to ensure stable and efficient model convergence.

+
+### Optimization:
+- Introduced **attention modules** for feature refinement, leading to improved performance:
+  - **CBAM (Convolutional Block Attention Module)**: Combines spatial and channel-wise attention to enhance feature selection.
+
+### Impact of Optimization:
+- **Training Loss**: Reduced significantly due to better alignment with class distributions.
+- **Model Precision and Recall**: Improved metrics after applying weighted loss and attention modules.
