Additional Notes:
The indicated number of lectures refers to 80-minute lectures. The syllabus accounts for 19.5 of 20 lectures of one quarter.

Source for compressed sensing: the paper and probably some more sources.
Recommended are take-home midterms or individual/group projects rather than in-class midterms.
