Day 43: Linear Algebra

Today:

• 6.5 homework due

• Sorry, I don't have the projects graded yet. I hope to have them by Friday.

• Current Business:
  • We continue our study of the SVD via the wiki.
    • Some applications over the web:
      • genome microarray
      • "Singular value decomposition (SVD) is quite possibly the most widely-used multivariate statistical technique used in the atmospheric sciences."
      • SVD and searching databases
      • This compression example shows that singular vectors look like sines and cosines

    • Example: #13, p. 481

    • Here it is in perhaps more detail than we wish to pursue: Section 7.4 highlights (pdf): The Singular Value Decomposition.
