Add Grad-CAM visualization for model interpretability #32
Description
Feature Request
Add Grad-CAM visualization support to highlight the regions in an image that the model focuses on while making predictions.
✅ Benefits
- Enhances model transparency and interpretability
- Helps detect spurious correlations (e.g., background patterns)
- Useful for debugging and demonstrating model behavior
Implementation Plan
- Use Keras backend + Grad-CAM for EfficientNetV2B2 & MobileNetV2
- Add example visualization in Week_3 notebook
- Optionally expose it in the Gradio UI
