Collected exercises on dimensionality reduction from various sources

Sources:

• CMU
• Stanford
• MIT
• David Sontag
• Radfod Neal
• an important source of exercises is LA4ML = a course from http://www4.ncsu.edu/~slrace/index.html; the link is no longer available; it was a course called "AA502, 2017, Linear Algebra", taught by Shaina Race, PhD, North Carolina State University

Directories/Files:

• "exercises" = the solved and proposed exercises
• "important_photos" = some proofs/ideas written by hand; there are mentioned in the pdf files where needed
• "practical exercises" = practical exercises
• "dimensionality-reduction-roadmap.pdf" = some theory regarding linear algebra or dim. reduction

Observations:

• there are typos
• the solutions were not modified; they are the original solutions from authors of the problem
• sometimes, there are some indications written in bold, or as Observations etc.
• there are some indications in red
• there are some problems by Alina Munteanu; they are marked by "BY ALINA MUNTEANU"
• in general, the order of exercises is good
• when I had some important observations, I wrote them near the exercise
