6. Supplementary Activities: Integration of SageMath

SageMath as an Interactive Supplement:

To improve conceptual clarity and align computations with theoretical understanding, SageMath will be integrated into the project using a containerized JupyterLab environment. This will allow the inclusion of SageMath’s symbolic and computational tools alongside Python libraries already being used in the project.

SageMath Environment Setup:

Using Docker/Podman:

• Base Image: sagemath/sagemath
• Extensions:
  • Libraries: numpy, scipy, matplotlib, pandas, seaborn, plotly, etc.
  • Machine Learning: torch, tensorflow, scikit-learn.
  • Symbolic Math: sympy, ipywidgets.
  • Purpose: Provide a unified, reproducible environment for all supplementary activities.

Example Services:

version: "3.9"
services:
  jupyterlab:
    image: sagemath/sagemath
    ports:
      - "8888:8888"
    volumes:
      - ./labs:/home/sage/labs
    environment:
      - JUPYTER_ENABLE_LAB=yes
    command: sage -n jupyter --notebook-dir=/home/sage/labs --ip=0.0.0.0 --port=8888 --no-browser

Weekly Supplemental Example Notebooks

SageMath will be utilized for reinforcing theoretical work in labs and projects:

• Week 3: Matrix Transformations (e.g., Reflection matrices with eigenvectors).
• Week 4: Homography Matrices (e.g., SVD decomposition of transformation matrices).
• Week 6: Fundamental Matrices (e.g., Properties of epipolar matrices).
• Week 9: Gradient Descent (e.g., Visualizing convergence paths in 3D optimization).

Markdown cells in example notebooks will guide users on running SageMath code snippets seamlessly. These examples will bridge computational and symbolic workflow gaps.

Advantages of This Supplementary Integration

1. Interactive Exploration:
   • Enables symbolic manipulation, visualization, and computational analysis harmoniously.
   • JupyterLab allows users to experiment within a familiar interface.
2. Reproducible Environment:
   • The containerized solution ensures a consistent setup for all users.
   • Persistent storage safeguards data across sessions.
3. Enhanced Learning Experience:
   • Aligns practical applications with theoretical concepts for deeper understanding.
   • Flexible design lets students explore topics relevant to their understanding.

Next Steps for SageMath Integration:

1. Phase 1: Containerization:
   • Build and test SageMath-based images.
   • Ensure compatibility of SageMath with Python libraries.
2. Phase 2: Notebook Development:
   • Draft and test weekly examples with explanatory markdown.
   • Focus on self-guided, intuitive notebook design.
3. Phase 3: Feedback & Refinement:
   • Deploy the environment and notebooks to stakeholders.
   • Incorporate iterative feedback to improve usability.
