Care to comment on changes made to SVD I and kNN lectures?

sladenheim commented 2 weeks ago

I noticed on the course notes webpage that kNN was producing a SyntaxWarning (https://tools4ds.github.io/DS701-Course-Notes/15-Classification-II-kNN.html). The minor change I made fixed it. It's because the latex inside of plots needs double \.

I changed the SVD1 lecture based on your comments in issue #143 to make the rank r match rank k.

I can always make more atomic PRs so that we don't group things together. I just figured I could fix those with this PR.

I addressed most of the comments except the ones that are unresolved.

I removed the height and weight example and show a synthetic dataset that has one direction with a lot of variance and another with less. This illustrates the point I was trying to make much better. I also removed the figure in the transformed space since it is not that informative. They see the transformed data with the digits example.

Let me know what you think.
