| bleg: shell inside emacs |
[17 May 2008|03:42pm] |
I have emacs for Windows, and when I do M-x shell, I get a DOS prompt.
But since I have cygwin installed, I'd like to get my cygwin shell instead.

David McAllester has publications on PL, planning, logic, learning theory, machine learning, NLP and "cognitive AI". I'm impressed.
I can see why people who work on planning or game theory need both logic and probability, preferably integrated.

| fake URL extension for Firefox |
[14 May 2008|09:54pm] |
From CMU, I can access URLs that I can't from home (e.g. http://psp.sagepub.com/cgi/reprint/33/3/325.pdf ). Sometimes, Firefox will reload when I'm home, losing the information. I'd like to be able to save the files onto my machine, and recognize the URL as that file (essentially a permanent cache). Doesn't Firefox have a lookup table that it uses for string replacement before sending the URL to nameserver? If so, I could add an entry pointing to the URL referring to my local file.
Better yet, find a way to train Firefox on which files are "gated", so that it knows to keep them in the cache forever, unless the user demands otherwise (i.e. answers yes to "Are you sure?").

| proof writing |
[13 May 2008|11:37pm] |
Writing mathematical proofs is a difficult, interesting art, and I'd love to look at the kinds of miswrites, fixes, rewrites people make.
The camera-ready copy is due in about 19 hours.
Here's the most important page:
Any suggestions?
Is it easy to make LaTeX render squares instead of "QED"?

| n-Rooks / simplex algorithm / bipartite matching |
[09 May 2008|12:16am] |
Someone has proposed a better solution to my "constrained n-Rooks" problem that I don't understand.
"constrained n-Rooks": return every possible assignment of rooks to squares on an n x n chessboard, under the constraint that no two rooks threaten each other, and that there are some given squares in which rooks can't be placed.
<< Define a graph with edge weights of zero or one, depending on whether or
not there is an edge. Bipartite matching can be written as an LP.
You find some solution to the problem. Now you want to find the other
optimal solutions. These solutions form a connected set in the polytope,
so you can just to breadth first search with coloring from any starting solution,
only stepping through other optimal solutions. >>
If you understand how bipartite matching relates to my problem, how it can be solved as above, and can explain this to me by this weekend, I'll buy you dinner.
I do not understand the Simplex algorithm.

| buying flights early |
[07 May 2008|07:46pm] |
Knowing that a lot of people will soon be buying tickets from America and Canada to Helsinki on July 3, should I expect to get a better deal if I buy early? Are the airlines aware of conferences like ICML (~500 people)?
Tangentially, Farecast doesn't work outside of America.

| paper style |
[07 May 2008|07:06pm] |
The first section of my paper is not titled "Introduction", because I want the title to be informative. I cannot think of any other papers violating this regularity.
Likewise, the titles of my sections and subsections tend to be long. Seems like a good alternative to having a "table of contents, in paragraph format and without page numbers (yechh)".
--
I'm also very fond of footnotes, it seems. There's normally a trade-off between accuracy/completeness vs. conciseness/clarity. Footnotes let me have both (by apologizing for the inaccuracy/incompleteness in the main text).

| sick, part two |
[07 May 2008|10:40am] |
Last night, my fever reached 103. Strangely, my only symptoms have been the fever, chills, thermal discomfort, etc. and fatigue (standing up was difficult), and a little bit of joint swelling (which I infer from a very slight pain): no coughing, no mucus, no stomach issues. And I only sneezed once.
A good friend came by to look after me. Since this has been going on for several hours, we considered going to the emergency room. I was not able to locate information of which hospitals my insurance will pay for. Apparently, if you're admitted into the ER, it's always covered. But this was a fuzzy line.
I also called the 24h doctor on duty, and she took 1 hour and 35 minutes to return my call. The operators kept saying it would be 10 minutes. Also, urgent care clinics in Pittsburgh inaccessible to those who don't have a car. (good luck getting a taxi!)
Call me spoiled, but I'm not used to this level of service. In Brazil, you can just show up at the doctor's office, and if it's late at night, we rely on family and friends who are doctors.
I've also been having strange thoughts during my "sleep": the same words kept cycling over and over again. Napkin... serviette... napkin... serviette.
Today, I have a doctors appointment at 3:30 p.m. I'm not better yet.

I am suddenly very very tired, with a high fever and my only option for being seen by a doctor today is to go to the ER. This sucks.
Maybe this was going around at Cornell.
I hit my head pretty good on Thursday evening (bottom of the swimming pool), but passed the concussion test (which I asked to get). I hope that's not related.

UAI: 32 plenary talks, 40 posters (total 72)

MLG seems interesting too.
4 conferences in one!

| algorithmic problem |
[05 May 2008|04:14pm] |
Given a set L of permutations of a list, compute the maximal partial order (DAG) under which all lists in L are topological sorts. How would you do this? Can you do better than O(m n^2 k^2)? (m = number of lists in L, k = # of things in domain = the size of the elements of L)
Sounds like an ILP problem.
One idea: whenever a cycle is detected, all the elements are deemed incomparable.

I'm going to Cornell tomorrow, mostly for the networking.
I should make a poster tonight.

| MediaWiki LaTeX still not working |
[30 Apr 2008|09:33pm] |
Also, the File Upload seems to want to write to the wrong place:
The upload directory (public) is not writable by the webserver.
I suspect they are related.
I can't believe how much time I've spent on this MediaWiki LaTeX issue. Maybe 15 hours in total. I just want to friggin pay someone to fix this for me, but I don't know where to find them.

[28 Apr 2008|06:11pm] |
My collaborators got me a studio on a different campus of the university. I'm also getting $1000, which I hope can pay for the flights (although currently, my best deal is $1228). Then there's registration fees: 650Euro, unless I can claim to be a student by the time I register (which I can't), in which case 365Euro.

<< The apartments are fully furnished with linen, cutlery and television. A HOASnet Intenet connection and cleaning twice a month are included in the rent. The cleaning doesn't include washing dishes and taking out the garbage. There is a laundry room free of charge in the building. Tenants may reserve a sauna hour in Hoas Viikki local office situated in Cubile (open Mon-Fri 1 pm to 4 pm). The sauna is located in the student dormitory just across the street. There is a parking place free of charge - please notify Hoas of your car registration number to avoid parking tickets. In all matters except the sauna reservations and parking, please contact Hoas Kamppi office. >>

I also found out that "plenary talk" means the whole conference will be watching me (my future employers, colleagues, etc.)! I'll want to practice it many times. Peter thinks it should be 25 minutes long with 5 minutes for questions. This is some serious incentive to try to run my method on real data... if I can find it! (Unfortunately, it seems economists usually publish summaries of their data, which make parametric assumptions)
In 2006, the proceedings published 72 papers. They had 26 plenary talks and 42 posters. (4 absentees?)
In 2007, there were 26 plenary talks (+ 4 invited talks) and 31 posters (that's 57 papers).
Also: << Note that all papers appear as full length papers in the UAI proceedings. The only difference between poster and plenary papers is the type of presentation at the conference.>>
In any case, it's exciting and scary!
