There will be 8 problem sets for CNS 187, not including problem set 0. Each problem set is posted on a Thursday, and is due a week later on the following Friday by 5pm unless otherwise noted. Problems sets should be delivered to the CNS 187 mailbox on the first floor of Moore. To review the grading policy for the course, click here.

*This is self-graded, which means that you must evaluate yourself the extent to which you understand these exercises. They should be straightforward review. Hand in your work in non-red, and write your self-evaluation in red.***This part is due Friday September 29th.** - In addition to problem set 0, after reading MacKay 38 and HKP 1.1-1.3, read the following two short articles:
autoencoders.pdf and
correlated_states.pdf.
Write a short (e.g. one page total) response to the papers, with the goal of succinctly identifying and
articulating what conceptual issues and subtleties you would need to master in order to be confident
that you could reproduce, generalize, evaluate the soundness of, and assess the significance of the work.
For each paper, pose five short questions to yourself that could provide a starting point to understanding
the conceptual issues and details that you identified.
**This is to be handed it on Tuesday, October 3rd, in class.**We will revisit these papers throughout the course; don't expect to understand them fully on this read-through, just try to understand the extent to which you understand them.
