So much to do - so little time

Posted in General, Research, Science on May 3rd, 2008

Sorry for the lack of activity here - an EPSRC grant with Riccardo came through, which is big happy news. The downside is that there’s a ton of research work to be done in a very short period of time. We were lucky enough to have Ellery Crane visiting for the last two weeks, and the two of us did some pretty massive hours while he was here. We got a bucket of really good work done was he here; we built several large new systems and got some early results that suggest probably at least a couple of papers.

I’ll try to post at least sporadically in the upcoming weeks, but I suspect things are likely to be light here well into the summer.

UMM students are just so cool!

Posted in Computing, Education, Events, My writing, Research, Sabbatical, Science, Writing on March 30th, 2008

EuroGP 2008 - 495
As mentioned earlier, our paper “Semantic building blocks in genetic programming” with Brian Ohs (UMM ‘08) and Tyler Hutchison (UMM ‘07) was nominated for Best Paper at EuroGP 2008 in Naples, Italy.

We won!

That a paper co-authored with two undergraduates from a small, public, undergraduate liberal arts institution like the University of Minnesota, Morris, could win an award like this at an international science conference is just too damn cool. Well done to both Brian and Tyler!

In the hectic melee of the conference, most folks don’t have time to do anything more than skim the nominated papers, and usually not even that. This makes the talks a crucial part of an award like this, as much of the voting is based on them. Tyler (pictured above at Castel dell’Ovo in Naples) was a huge help in that regard. He flew over to the UK several days early so we could work on our talk, giving us the time we needed to revise and practice. He also produced a super cool little six page comic with a nifty introduction to our work that the audience could follow along with. We did a joint presentation, each covering about half the paper. Our talk was well received, and Tyler’s comic was incredibly (and deservedly) popular, and there’s no doubt that his participation was a huge help.

(And all this is on top of Brian and Tyler’s hard work and contributions on the paper itself. Obviously without that content we never would have had the paper accepted or nominated in the first place. So they both deserve huge kudos for that as well.)

Friday morning our paper was voted Best Paper by the conference attendees, and we were presented with a certificate, a box of Italian lemon cookies, and a box of Irish chocolates. All the Best Paper winners from the various EvoStar conferences and workshops also got to choose a free book from the Springer table. Tyler got a really cool book enitled Leonardo’s Lost Robots, and I got The forgotten revolution: How science was born in 300 BC and why it had to be reborn. (It was all terribly liberal arts of us - pretty much everyone else took evolutionary computation/artificial intelligence books of one form or another.)

Tyler upheld a fine tradition of our students making UMM look really good at conferences like this. From his deportment and grasp of the material, most people assumed he was a graduate student, despite the fact that the looks like he’s about 16 :-). He’s currently doing contract work as a web developer and designer, but is seriously interested in going to graduate school in the near future, and he definitely impressed the folks at the conference. I’ve been really lucky to work (and co-publish) with a string of great UMM students, and am looking forward to continue that with a very sharp student named Sara Lahr when we get back.

The trick for me (sometimes) is remembering just how good our students can be. The room we spoke in was this grand space of inlaid wood and marble that was quite a surprise in several ways. This was made worse by the fact that we were in the first session, so we had very little time to adjust and adapt. I was worried about running long (we had a lot of material to cover), and started to lose my nerve about having Tyler wandering around the room at the beginning handing out the comic. Tyler was really calm and collected about it, though, talked me down, and everything did in fact go really smoothly. The moral? Handouts are Good, really cool comics handous are Even Better, and I need to remember to listen to my students :-).

Thanks a ton to Brian and Tyler and all the people and offices at UMM that supported our work, and everyone who voted for our paper at EuroGP! Special thanks also to Riccardo Poli for hosting me on this sabbatical at the University of Essex. I’ve gotten a ton of cool work done here with Riccardo, including “A linear estimation of distribution GP system” at EuroGP, which was also nominated for Best Paper (and which I suspect was also strongly in the running).

I’ve dumped all the photos Tyler and I took in Naples onto my events account on Flickr. I’ll try to clean up a few to post to my main Flickr account in the next week or so.

A heck of a party!

Posted in Books, Computing, Education, Events, My writing, Research, Sabbatical, Science, Writing on March 27th, 2008


Last night’s unveiling of A Field Guide to Genetic Programming was a huge success! We had one of the poster “stalls” with 50 copies of the book that we’d purchased from Lulu as our initial “print run”. We were wearing cool t-shirts sporting that wonderful cover, had the nice poster shown to the right, and even had spiffy postcards with the cover to give away.

The book was a big hit with the Evo* crowd, and we sold out the full set of 50 pretty quickly. Lots of folks had us autograph their copies, many of which are now destined to be collector’s items with the signatures of all three of the authors. Some even have the signature of Tyler Hutchison, who did the nifty cover art for us and helped a lot with the roll-out.

There were tons of photos taken at our booth, including candids of us signing and working the crowd, and posed shots with our cool Field Guide shirts. People have promised to send us photos and links, so check back in the next week or two for some of the finest in EC book release amateur photojournalism! (And if you’ve got a photo from the event, or a nifty shot of your copy in its place of pride on your bookshelves, please pass it along.)

As mentioned before, the book is now officially released and available to any and all via lulu.com, both in an inexpensive printed form (what we were selling last night) and as a free downloadable PDF.

So go check it out - 50 whole Field Guide fans can’t be wrong!

Nothing like a little shameless self-promotion

Posted in Computing, Education, Photography, Research, Sabbatical, Science, Travels on March 10th, 2008

Choosing two points at random

I’ve been sitting on this for a while I waited for EuroGP to get their web site updated; they have, freeing me up to do a little unabashed chest-thumping, leavened with some praise for UMM’s excellent students.

A few weeks from now the Eleventh European conference on Genetic Programming (EuroGP) will happen in Naples Italy. The only other time I’ve been to EuroGP was in 2001 when we were here on sabbatical the first time. I really love the conference, and it’s small and intimate and tends to have a really high signal-to-noise ratio. Unfortunately, it’s also an expensive flight from Minnesota for a three day event, and the timing tends to be really awkward in my teaching schedule, so I’ve never made it back. One of my many fond memories of that conference was winning the best paper award with Riccardo Poli for a pair of papers we’d written together as part of that sabbatical visit. Lake Como and the Alps (Oddly, both times I’ve attended have happened to be the only two times it’s been in Italy. The little photo is from the 2001 event at Lake Como.)

The best paper nominations for this year’s event have been released, and I’m quite excited that both of the papers that I submitted this year are on the list. One is another join project with Riccardo, and the other is a paper with two UMM undergrads: Brian Ohs and Tyler Hutchison.

That’s Tyler in the photo up top, presenting some work he did with Andy Korth and I that won the best student paper award at MICS a year ago; Tyler also did the cover illustration for the forthcoming book Riccardo, Bill Langdon, and I are just wrapping up. In a big happy, Tyler was able to pull together the funds to fly out for the conference, so we’ll be able to do a joint presentation enlivened by his presence and cool drawings. Unfortunately Brian can’t make it, but it’s cool that Tyler can; this will be the first of my students co-authors that’s made it to a European conference with me.

The competition is gonna be tough for the best paper award, including a very nice paper by one of Riccardo’s students (Stephen Dignum). Fingers crossed!

The full program is also now on-line (as a PDF) — it looks like some cool material. I’m quite looking forward to the conference, although I must say I’m a bit nervous about the ongoing trash crisis in Naples (here and there).

Not quite a wave

Posted in Art, Computing, Mathematics, Research, Science on March 6th, 2008

Not quite a wave

Sometimes you’re just minding your own business, trying to get a little science done, and a little art pops out at you all unexpected.

What?!? You want to know where this comes from? All is revealed beneath the fold…

JOCP! At revision 400!

Posted in Books, Computing, Education, My writing, Research, Science, Writing on February 28th, 2008

Revision 400 screenshot

It’s pretty cool when you update your repository and see

At revision 400

We just hit that on the genetic programming book that Riccardo and Bill and I are working on; we’re currently averaging close to 10 commits a day here in the final stages. We hope to wrap it up in the next 1.5 weeks and then off to the printers for fun (and no profit in the traditional sense)!

P.S. Anyone want to proof read a few pages? Get in touch and we can work something out.

You know, basic editing and lit review = teh good

Posted in Computing, Education, Research, Science, Writing on February 27th, 2008

Just finished my GECCO reviewing, and I must say that is seriously sucks when people don’t attend to even the most basic of issues. Two things almost guaranteed to majorly annoy a reviewer:

  • Weird random floating fragments of text that are obviously the disemboweled remnants of some cut and paste action.
  • Only 8 entries in the bibliography on a subject that has been heavily researched for over a decade.

And just guess the average publication date of 8 fine references.

1985.

Yeah, over 20 years ago.

3 entries were books (two of which were over 10 years old), and the only 2 journal articles were from 1938 and 1964 respectively.

Strangely enough, I didn’t encourage acceptance of that paper.

The really depressing thing is that most of our (undergraduate) students at UMM would do better than this.

No, maybe that’s the uplifting thing.

Maybe the really depressing thing is that I see papers with this kind of bibliography fairly often. I’d almost recommend some sort of automatic rejection system for obviously stupid bibliographies, but then people would just start padding their bibliographies with random citations to get past that blockade.

Sigh.

N-grams and the evolution of programs

Posted in Computing, Research, Sabbatical, Science on February 2nd, 2008

Which of the following was written by (a) me, (b) William Shakespeare, and (c) Charles Darwin?

“I would have sent to Rome that’s worthy death?”

“The naturalist looking at species as he might succeed from a fork low down in the separation of the species of any species in a more or less from their sap this is unimportant for the instincts already possessed by certain plants so that natural selection of mere piles of superimposed strata and watch the sea separating an island even if we believe that pure water can effect little or no offspring.”

“The troubling aspects of a building block semantics in a given tree in the context and false.”

The answer and (much) more is below the fold.
