Extra Credit Question

Inspired by an idea bandied about in wondergurl_77's LJ by yahvah, I put the following question on my CIS 732 (Machine Learning and Pattern Recognition) final exam yestrerday:

Describe how you would go about building a hierarchy of concepts or lower (domain-specific) ontology for a weblog (online journal) or topical web site. You may suppose that you have access to other electronic encyclopedias and dictionaries, as well as a live feed of the site (e.g., via remote syndication service). Sketch your design as concisely as possible.

Knot exacterly the queastion yahvah was posing, but interestingly, people spent more time on this little extra credit question than on problems worth five times as many points.

So, yeah, it's lal yahvah's fault. 8-) :-D ;-)

I'm finished grading!
(Everything for CIS732, everything but term projects for CIS730.)

Edit, 01:40 CST Fri 19 Dec 2003: As celandineb, another professor, wrote recently...
(best Smeagol voice) I'm fweeee!


From celandineb... thing is, those Coke bottle glasses look unnervingly like my nold ones.
Come to think of it, they loonk a lille like my current ones! 8-D

I'm curious if you got some intriguing answers?

(After having spent much time sifting through pre-built KM modules, I'm still thinking about how affections would look in a knowledge base, which I find to be crucial for any attempt to psychoanalyze a LJ or weblog.)

Yes - one that was longer than any other answer the prro guz wrote on the whole tsarking 200-point exam! (He earned an 'A' in the curse nazwaz, so dknot feel too srroz fro him. :-D)

I laso gont an illustration (block diagram of a proposed system) which unfortunately didn't have the prose detail to go with it, but hey, I have ways of making students talk. ;-)

Nazwaz, I will check with them individually to see whether each is willing to have his answers psotted.

Modulo a few special cases such as everybuddy putting "quixotic" as their mood, you'd prolly get more mileage out of the annotations (mood icon, LJ pic keywords, and the little thumbs-up/star/deeath's heead thing). And neverunderestimate the power of an empticon [wreal Tyope]. 8-)

I'm going to post a journal entry on what I've got going on my head. I'll have to take some more time to think about it. Once I'm done, I'll enjoy your comments. :-) You can tell me whether I'm an asshat or not. ;-)

I'll tell you wot I think, including whether I think your idea will fly, but true asshats are few and far between when it comes to off-the-cuff ideas. It's sifting the few real gems (more germ than chaff, to mix metaphors) out of the "nifty idea, but probably more trouble than it's worth" that's difficult, and too often hit-and-miss for the reviewers themselves.

I was searching around for Maxfield Parrish images yesterday and found this one and iconized it... I just have way too much fun with my icons. Take it, if you like!

Also get writer's block - this dratted article has been hanging over my head for several months. I wasn't able to get something through ILL that I was hoping to use, so am having to rethink what is going into it.

My muses are capricious - it's always the ones I don't have time for who come and sit on my shoulder, whispering insistently that I just have to write XYZ... the ones that I need to have help from stay away, whatever bribes I offer!

Interesting; I've never heard of Parrish until now, but then I'm dirt ignunt aboat most non-Tolkien/non-SF artists. Nasmith's and Whelan's work memind me of his.

Take it, if you like!
Thanks fro the offer!
I think I will hold orf on adding naz gnu icons until I'm sure I can either fend orf the urge to go overboard and make 1050 (which is wot I have felt like doing if I get a paid account). It's frequently lal or nuffink with us emo philosopher-poet geenkstronkies, is wot.

Re: Oi, oi...
Waut... are yew sazing yore account is FWEE?
Yesh! Eet lawaz has been.

That you, who, in evil alliance with Lala, provoked me into getting one of deze? And that Eye paid fro it and yew dinna? That yew dnot have fifteen icons, let alone fifty? )And besides, you gent fifteen on a paid account, and more of yew paz mroe. Bha. But fifteen will do for now.)
Um, I provoked yew into getting an account, but knot the 15 or more. But seriously, I'm knot refraining from getting a paid account out of stinginess - in fact, I was about to do it when they went from 10 to 15-50. Problem is, customizability is the Bane of Existence to a Jedi hobbit with too muchno time on his hands.

Yeah, I gno. I sowwy.
I twitch a lille myelf when I think aboat it.

I'm just surprised that you, an LJ promoter, didn't go intimate with it yet.
Uh, wlel, see... er, hehe... that is...

As for too much time on one's hands... I spent the whole of last night embedding the bugger into thereisnoy. Might finish tomorrow. *sigh* ;)

No kidding.
I reckon we could take this place over if everyTEUNC gont ninvovled....

That is a truism - or ataleast an axiom cf. TEUNC's enemees online being legion. Fro naz online organization, participation by a preponderance of TEUNCs is sufficient to trask it.

Hey, I'm an undergrad computer science/mathematics student at the University of Southern Mississippi. I do work in scientific computing and visualization, and I found your journal by searching for "scientific visualization" in interests. Mind if I add you to my friends list?
Also, what are the "hot topics" in sci-vis right now? I'm looking for a project and I have no idea where to start. I just got moved from a different group that was doing VR stuff.

Be my guest!
Hey, I'm an undergrad computer science/mathematics student at the University of Southern Mississippi.
Hrm, my dad attended USM and worked as a teaching assistant in Chemical Engineering there for a year, in the 1960s.

I do work in scientific computing and visualization, and I found your journal by searching for "scientific visualization" in interests. Mind if I add you to my friends list?
Sure, be my guest. The more CS people, the merrier!
(Wlokay, maybe merrier isn't quite the right word... tronkier, anyhow. :-))

Also, what are the "hot topics" in sci-vis right now? I'm looking for a project and I have no idea where to start. I just got moved from a different group that was doing VR stuff.
Serendipitous, that.
We just abandoned reasonVRML for madnessJava3D ourselves in the Multi-Robot Simulator project headed up by Scott DeLoach, whom I work with. As you may have seen on my research lab page, I teach the Computer Graphics course at KSU-CIS. It's mostly a 3-D photorealistic rendering (shading, raytracing, radiosity) course with a little on infovis, fractals, and a tiny bit on particle systems and animation.

I would say that hot research topics in sci-vis include visualizing:


  • high-performance systems - system performance, network utilitization, parallel and distributed Grid computing, etc.

  • anatomical and physiological structures - especially functional magnetic resonance imaging or fMRI

  • macromolecules - esp. proteins, lipids, nucleic acids from bioinformatics

  • mathematical objects and machine learning models - higher-dimensional objects, output from data mining: e.g., self-organizing maps (SOM) and principal components analysis (PCA), independent components analysis (ICA), support vector machines (SVM) and other kernel methods



Sorry for sounding so generically unimaginative and prosaic above. I could tell you more about our research, but then I'd hafta trask you. ;-)

(Seriously, we can always take it offline to my research mailing lists if it gets too close to the bleeding edge. Or, if there is interest, I'm usually open to discussing things in semi-public fora such as this.)

No! You can't do that!

In combination? Or just severally?

Oh, there are no rules. I just meant that if it got to a 200-post thread, it might be a lille daunting to our less tronkie friends to wade through, but they'd prolly quit as soon as the blasting firemaximum margin techniques were brought to bear.

Re: You know no pain, you know no risk
Whoops, my HTML skills are pretty crap. Well, no, but my *attention* to HTML tags is pretty crap. ;-)

I wouldn't want to taste support vectors. They'd probably be all cottony without even mint or anything. *paugh*

I always do as I please, but thank's for telling me to feel free about it anyway. Harrumph!

Just severally. Though I was considering making my NN project (a WinAMP plugin that "recognized" [after training in MatLab and export of the "learned" matrices {RBF-based apprach} to C source]) into a 3D viz plugin ... but the results were even WORSE than I imagined ... and I was imagining a total failure of it to do anything anyway. I still laugh when I think of that.

Maximum margins? For optimal plane placement on linearly-seperated data? Damn, man, that's hardly blasting fire! ;-) Gimme symbolic representations and a formalism to operate with them, or give me DAY-UTH!!!

Re: How in Udun did I get this?
I was actually popular in highschool.
Wlacksherly, so woz I - one of the popular geenks by virtue of notoriety. My classmates delighted in writing limericks and pomes aboat my cwazy-scientist hair style and geenky clothing. Laso, they lurved to throw strange twists of irony in my path, such as voting me one of the class heartthrobs - as a joke, to be sure.

I got into a fight with a prof right at the start, I drew eople temporary tattoos (with waterproof markers), I was allowed to draw on classroom walls (the 'frescoes' are stll there :D), I was a Goth gril and won the school some awards, in fact, I'm still a Hippie-Raver-Goth gril and work at my Uni.
See, I dknot think that's wot it was.
Didja notice that lal the morbid answers were mapped to "outsider"?
Amy Lee of Evanescence memarked in a recent sound-bitten interview on Yeehaa Launch that she was lawaz an outsider but knot a Goth:

LAUNCH: Do you consider yourself a Goth, or an outsider type?

AMY: I know what you mean, but those two things--"Goth" and "outsider"--don't have to go together. I mean, I definitely have always been an outsider, but I wasn't dressed in black all the time, slitting my wrist in the corner, cutting myself. Never! I wasn't that person. I was definitely on my own a lot. I was an advanced art student, and like, really into it. Like, I would just go in the hall every lunch and just be making pieces of art. Or I was choir president. You know, I was a dork. But not in the way of, "She's one of the nerds." It was more like, "Who?" I really just made a big effort to dress down, and I didn't talk to a lot of people. I had one or two intimate friends, and that was it.


Hmm. I could say that we TEUNCs defy stereotypes, but since you agree with your quiz results, I'm a lille unsure... ;)
Dknot wrroz - mirabehn is wright: most hmunsa defy stereotyopes. Which is knot to saz there aren't trends; that's where a lont of categories come from. But epople can surprise yew if you let them.
