This function adds (max-min)/50 noise to each sample in a data set. This tends to be a very small amount, but if its still too much, an amount can be specified as a second parameter. This is nice for working with QDA, and LDA where singluar matrices can be produced when some of the rows or columns in the data are constant across all samples. Using this jitter function on the data before standardizing it and using it works … text/html 2008-05-12T10:06:37-07:00 Brent Wilkins http://www.cs.colostate.edu/~anderson/cs545/wiki/doku.php?id=latex_discussion&rev=1210608397&do=diff Embedding Animations in PDF's / Makefile I just thought that I would share two things that I found useful using the tools for this class on another class. First is the ability to create video from a directory full of images (I.E. from R) and then to embed that video into a PDF. Making movies from images (PDF). One thing to note is that the files need to be named 0001.jpg, and not just 1.jpg in order to be sorted correctly. Next is a Makefile that claims to do all sorts of error message pars… text/html 2008-05-07T00:22:30-07:00 Jeshua Bratman http://www.cs.colostate.edu/~anderson/cs545/wiki/doku.php?id=assignment_7_discussion&rev=1210141350&do=diff Extended Due Date In case you didn't look at the announcements page today, the due date for assignment 7 has been move to Thursday. --- Jeshua Bratman 2008/05/05 14:35 Anyone having good results? I'm still struggling to find parameters that work in my neural net version of HW7. I'm assuming I have an implementation error in my code, but just in case I thought I'd ask if anyone has theirs working acceptably well. (With “acceptably well” meaning something like what we discussed in class l…
