May 15, 2002:

• Extra class is at noon today in our usual room.
• Solutions to Problem 3 of Problem Set 4, by Paul Simbi, was distributed in class on May 1.

April 16, 2002: Problem Set 4 is now complete. If you downloaded or printed this problem set this afternoon, please check that you have the final version. An incomplete version was erroneously posted for a few minutes this afternoon.

April 3, 2002, 2nd entry: Solutions to Problem Set 2 are now available online.

April 3, 2002:

• The take-home exam will be available by hardcopy only, starting tomorrow at 9am. If I am not in my office, my secretary, Mitra Kelly, in room 323 will have copies. The exam is due 5pm, Tuesday April 9, 2002.
• Hardcopy solutions to Problem 4 of Problem Set 1 are ready and will be handed out in class today, as will your graded papers.
• Solutions to Problem Set 3 will be available by hardcopy in class today or online after class.
• ERRATA to solutions for Problem 2b of Problem Set 1: The discussion is fine, but I get different actual numbers:
  D_q S=[.05, 1.11] (compared to [0.167, 2.82] in the solutions).

March 9, 2002:

• Hardcopies of solutions to Problemn 1 of Problem Set 1, by Jeffrey Bigham, were handed out in class on Wednesday (3/6).
• Since my schedule did not permit timely posting of Problem Set 2, the due date is being extended. Check back for the posting of problems and due date.
• Please see new readings posted for 2/25 (under "Also of interest") and for 3/4 and 3/6.
• We will have a guest speaker Monday (3/12): George Tzanetakis will talk about his work on audio (music, sounds) information retrieval

March 4, 2002: Hardcopies of solutions to Problems 2 and 3 of Problem Set 1, by Ben Haskell, were handed out in class today. See me for a copy if you did not get one.

March 3, 2002: A brief project proposal is due tomorrow. An email paragraph is sufficient. Anyone who is still at a loss for a project idea, should make an appointment to see me (Prof. LaPaugh) this week.

February 21, 2002: Problem 4 of Problem set 1 was added Tuesday (2/19) night. This completes the set of problems.

February 18, 2002: I will hold office hours on Mondays and Wednesdays right after class (12:20PM) until 1PM. I often am available later than 1PM, but cannot guarantee it. If you prefer to make an appointment for another time, catch me after class or email me. You are welcome to stop by my office to make an appointment, but since I split my time between my CS office and my Forbes office, it is harder to just catch me in.

February 18, 2002: Problem Set 1: 3 of 4 problems are now online.
