Sep. 16 Problem 2 in assignment 1 needed some slight corrections, the new version is posted now.
Sep. 22 It has come to my attention that we only have a limited number of licenses for Matlab. Thus if have finished using Matlab, please exit the Matlab program so that other people can use it. Also the gaul (undergraduate) network has more licenses than the graduate network. If you are a graduate student and can't run matlab from a graduate lab, try going to the undergraduate lab.
Sep. 27 Lecture 3 slides are now corrected. Instead of 6.63 for the case of ML classifier it should have been 6.70. This correction should be made to slides 28, 30, 34, 53. Your slide numbers may differ from mine, if you do not have the most recent version of the lecture.
Sep. 27 Office hours this Wednesday, Sep. 29 will be held in room 300. Please come to see me if you have any questions about homework, which is due on Monday, Oct. 4.
Sep. 27 Correction to problem 1: Correction to problem 1: I forgot to mention that when you plot the histogram, the value at each bin should be divided by the bin width (in addition to dividing by the number of samples). If you do not divide by the bin width, you are plotting the probability mass function for the distribution of samples. To get the approximate density function for these samples, you need to divide by the width of each bin. Why you also need to divide by the width of each been will become clear after the lecture on Monday. Since I have discovered this bug rather late, if you are done with the homework and do not wish to correct it, you can hand in your solution as is without any penalty.
Oct. 7 Solutions and matlab code for Assignment 1 have been posted under October 6 in the schedule.
Oct. 12 Assignment 1 due date is extended until Wed., October 20, and also I won't apply late penaly if you hand it in by 4pm Friday, October 22. You should try to finish it by the 20th though because there will be a new assignment given out on the 20th.
Oct. 12 I have to move my office hours on Wed. Oct. 13. to 2:30-4:30.
Oct. 12 It is time to start thinking about the final project .
Oct. 25 I've changed the assignment and final project schedule. Assignment 3 is now due on Nov. 10, Assignment 4 is due on December 1, and there will be no Assignment 5. The schedule for the final project is as follows:
Oct. 28 I had to make some changes to problem 2 of assignment 3 because generalized eigenvalue solver does not work well in Matlab.
Nov. 1 Part (e) and (f) of problem 1 in assignment 3 has been clarified.
Nov. 3 For assignment 3, make sure you use [V,D] = eigs(). If you just say V=eigs, this function returns the eigenvalues in column vector V. If you use [V,D] = eigs(), then it returns eigenvectors as columns of V and eigenvalues on the diagonal in D.
Nov. 3 I have corrected the "non-sample" midterm and solutions, and I will put them in the envelope on my door. Nov. 16 Teaching evaluations will be conducted on Dec. 1 at the end of the class
Nov. 29 Correction to lecture 13, slide 24. For the "true" gradient descent, the input-to-hidden weights w's should be updated first, followed by update to hidden-to-output weights v.
Dec. 8 Unfortunately I lost all the data for your final projects, so you need to resubmit it again. You can email it to me, or if it's large, put it somewhere on the web for me to download, or on a CD-disk.
Dec. 16 The final grades are posted
