Laptop for the mid-terms

Just wondering, does "open book, open notes" mean we can bring our laptop, as long as we disable the wireless?

Reviewing topics covered

Here is a hint: For each class, along with the audio links, I had put a reasonably verbose description of topics covered in that class. If you read those descriptions, that should give you a "summary/review" of what happened.

For example, here is the description of what happened in Lecture 10--directly from the notes page

L10 Audio of [Feb 18, 2010] (***THE ADVANCED LSI LECTURE***) Lengthy recap of LSI analysis; discussion of class blog questions; discussion of relation between LSI and feature selection (feature selection looks for just subspaces of existing space); LSI and LDA (LDA takes the "class" information into account LSI doesn't know what classification you might be attempting); LSI and nonlinear dimensionality reduction (one idea is to first blow up the dimensionality and then find a lower-dimensional hyperplane in this blown up space. So, you might go from 20-D to 300-D and come down to 4-D).

"decisions are made by those who show up"...

Re: (*Correction*) Important: Schedule for midterm

Yes, you are right. I changed the URL in the homework problem.

Professor Rao,

On part 2 of question 3 on the homework the website listed doesn't work. I think that it is: http://academic.research.microsoft.com/CSDirectory/Author_category_5.htm

[[Looks like I was not looking at the calendar carefully when I typed this mail--it would be reasonably hard for me to survive your collective ire if
you have to  come back in the middle of your  spring-break revelry to submit the homework. So here are the new dates:

Homework 3 due: 25th March
Exam:  30th March
Project part 2 Due date:  *shifted* to 6th April

Looking ahead, project part 3 will be due by 4th May, the last class, and will have to be demonstrated to the TA in that week.

Dr. Rao : Think Cap!...

Dear Dr. Rao

In page rank can we make a node as sink that is having "n" inbound links but one outbound link to itself?

What is A+Z matrix for that?

I figured out that If there is any node with only one link to itself then we have to omit 1 in the column of A corresponding to that node.

But in Hub/Auth we can't omit that 1.

In page rank we have to omit that 1 otherwise A+Z will not be a stochastic matrix.

Page rank is independent of self links.

Is my inference correct?
