Kei Shun Ma - congrats on the Data Mining competition. I have a quick question for you - can you possibly contact me on p.ellegaard@yahoo.com

Thanks Peter

Hopefully you've all picked up HW4&5. If you find any grading errors, email me - I'll probably have you make a note and stick it in my mailbox.

I should be getting project grades to you over the next couple days.

It's been a pleasure!

hey matt, even though he said only parts 1-3 are relevant, do you expect we will need to be able to work out problems like the last page of the sample final: http://www.cse.ucsd.edu/classes/sp07/cse15...ead-problems1-3.pdf

Yes, the last problem on that final is relevant - sorry I missed that!

-g.

I have posted all of the lectures, and a couple
of relevant tests...see you tonight!

Hi folks --

If you haven't gotten an email from Matt yet, here are
the answers:

As mentioned in class, the review session is tomorrow, Monday,
June 11, at 7PM. Our plan is to have it in the same room as
last time, in the basement of EBU3B, just opposite the elevators.

You can have one two-sided cheat sheet for the final.

I plan on posting the slides from the last k classes tonight,
as well as a practice final, at least as close as I can come
to one under the circumstances (somewhat different material,
etc. from the last time I taught it).

cheers,
g.

I would also like to know this

when is the final review????????????

I think when we were discussing the cheat sheet for the midterm we came to the conclusion that we could have a 1-sided cheat sheet for the midterm and a 2-sided cheat sheet for the final.

Are we allowed a cheat sheet? One-sided?

Will we have any final review and lecture notes posted online?

If it's in the training set, it's perfectly legit to just add more feature words based on your performance... Feature selection is a bit of an art, not a science (at least at this stage - more scientific and principled approaches to feature selection are pretty active areas of research).

Wondering what everyone is getting trying to classify the test sets?
For us, currently:
trainSpam4 = 99.14% correct
trainHam3 = 77.13% correct

We are having a tough time classifying ham messages as ham, especially ones that are not written by a human and short messages that do not contain any of our feature words. Any suggestions.
