  • Simplified PCA implementation by initializing and fitting PCA for each number of components within the loop.
  • Removed redundant transformations and reconstruction steps, enhancing code clarity.
  • Updated comments for better understanding of the PCA process and its visualization.
  • Improved the display of reconstructed images and compression ratios.

Summary by Sourcery

Simplify the PCA implementation by initializing and fitting PCA for each number of components within the loop, removing redundant steps. Update comments for clarity. Add a new transformer-based addition learning model as an educational example, demonstrating the application of attention mechanisms to arithmetic operations.

Enhancements:

  • Simplified the PCA implementation by initializing and fitting PCA for each number of components within the loop, removing redundant transformations and reconstruction steps.

Documentation:

  • Updated comments for better understanding of the PCA process and its visualization.

Reviewer's Guide by Sourcery

The PR introduces two main changes: a simplification of the PCA implementation in the MNIST example and the addition of a new transformer-based model for learning arithmetic operations. The PCA changes focus on code clarity and efficiency by removing redundant steps, while the new transformer implementation provides a comprehensive example of using attention mechanisms for mathematical operations.
