Phase 1 — Python & Math

April 28, 2026

Continue learning Mathematics for ML and Python crash course

What I Did

  • Completed week 4 of the linear algebra part in Mathematics for ML

What I Learned

  • Learned about Variance and Covariance and how they related to spread in a dataset
  • Learned about Covariance matrix and how they can be used with Eigenvalues and Eigenvectors for dimensionality reduction
  • Learned about projections as a linear transformation(projecting a higher dimension dataset to lower dimention)
  • Learn about Principal Component Analysis(PCA) which can be used to reduce dimensionality of datasets without losing too much information

Bugs & Blockers

  • None

Concepts That Need More Time

  • N/A

Tomorrow

  • Finish the last programming assignment for week 4 of the Mathematics for ML(Linear Algebra)
  • Continue reading my Python crash course book(I only need to do the project part)

Wins

  • Completed week 4 of the Mathematics for ML(Linear Algebra)
