5:45 am	Slooowly working, but it's working! After removing the final arithmetic error, my program Rohan is producing correct results both on the GPU and the CPU, and evaluates a 9x36x1 neural network in 220 microseconds on a single thread. This, however, is very slow, as the 10,000 sample learning set takes a total of 2.2 seconds to complete, while the CPU can do it as quickly as 0.67 seconds (all numbers from my home machine). So, I am currently working on making multiple threads go at once. This is not as simple as making copies of everything, as each learning sample involves 10 values expressed as a double and a double complex each (24 bytes x 10 x 10,000 ~= 2.4 MB), and the 10x36 + 37= 397 weights are double complexes (16 bytes x 400 = 6400 bytes which is no biggie but it adds up) .  With about 1000 MB ram on the card, the "multiply and conquer" method would support at most 40 simultaneous evaluations; the x40 speedup would yield a total evaluation time of .05 seconds. I believe that a better approach is to treat these as textures, so that all threads can share the same 2.4 MB of learning values "textures", and the 6400 bytes of weights can be both shared as textures for reading, then altered individually for backpropagating. I'd also like to note here for posterity that in building the Boost.org binary libraries for Visual C++ 2008, the file that controls static and dynamic linked versions is boostcpp.jam in the $BOOST_ROOT directory, specifically the section where "self.minimal-properties-win" is defined.

1:50 pm	I live the dream! Part II I work in a machine intelligence laboratory that physically used to be a study lounge. The semster we moved in, I printed up a sign with our official title and the common internet graphic of a skull x-ray with a circuit board visible inside the cranium to cover the existing placard, in hopes of distracting people into reading the sign before they barged in, expecting an open study lounge. Later the same day, the sign had been removed and I was cautioned that it was inadvisable to have such a thing to remind the other staff who had been against the reallocation of the space that they had lost the issue. People occasionally still wander in looking for the study lounge but the general craft room decor tips them off. So thanks to university politics, I don't just make artificial brains, I work in a secret laboratory making artificial brains. Current Mood: accomplished (Comment on this)

9:03 pm	I needed to Science some more! The second publication to which I have contributed is appearing at SPIE 2011 this week. "Intelligent edge enhancement using multilayer neural network based on multi-valued neurons" This is something of a coup for myself and the other undergraduate authors. Not only is it unusual to be published before grad school (of course, since there's no Computer Science grad school here yet...), this is the second publication for most of us, which is one more than several university faculty members have.

6:50 pm	I needed to Science! It's been a few months and no one has called to say our paper was approved for publication by mistake, so.... > @article{ 10.1109/AMS.2010.53, > author = {Visvasuresh Victor Govindaswamy and Matthew Caudill and Jeff Wilson and Daniel Brower and G. Balasekaran}, > title = {Clump Sort: A Stable Alternative to Heap Sort for Sorting Medical Data}, > journal ={Asia International Conference on Modelling & Simulation}, > volume = {0}, > year = {2010}, > isbn = {978-0-7695-4062-7}, > pages = {227-230}, > doi = {http://doi.ieeecomputersociety.org/10.1109/AMS.2010.53}, > publisher = {IEEE Computer Society}, > address = {Los Alamitos, CA, USA}, > } > > Visvasuresh Victor Govindaswamy > Matthew Caudill > Jeff Wilson > Daniel Brower > G. Balasekaran > DOI Bookmark: http://doi.ieeecomputersociety.org/10.1109/AMS.2010.53 > Sorting data sets are a thoroughly researched field. Several sorting algorithms have been introduced and these include Bubble, Insertion, Selection, Shell, Quick, Merge and Heap. In this paper, we present a novel sorting algorithm,named Clump Sort, to take advantage of ordered segments already present in medical data sets. It succeeds in sorting the medical data considerably better than all the sorts except when using totally non-clumped data. In this test using totally nonclumped data, Heap sort does only slightly better than Clump sort. However, Clump sort has the advantage of being a stable sort as the original order of equal elements is preserved whereas in Heap sort, it is not since it does not guarantee that equal elements will appear in their original order after sorting. As such, Clump Sort will have considerably better data cache performance with both clumped and non-clumped data, outperforming Heap Sort on a modern desktop PC, because it accesses the elements in order. Sorting equal elements in the correct order is essential for sorting medical data. http://www.computer.org/portal/web/csdl/doi/10.1109/AMS.2010.53 Edited to Add: While the subject of the paper isn't a big deal outside the database community, it is my first publication, which is a big deal considering some of the professors here have only one publication as well. My colleague Matthew managed to be party to another paper accepted for publication before he graduated, as well as being on the team that took first place in Computer Science at last year's Pathways symposium, which is not bad considering we were up against numerous other schools up to 40x our size! A&M-Texarkana took second the year before that, and we hope to do well again this year. Current Mood: accomplished (Comment on this)

12:44 am	Toot! Look at me! Say good things about me! Tooooot! I kept putting off posting my spring grades until now I have summer grades and am beginning my final fall semester before graduation. Alas, I did not repeat my all-A sweep of the previous fall, or my full-semester-in-a-summer stunt from last summer.

2:15 pm	Argh! So, somehow someone lifted my debit card's number and ran with it, but the bank caught it and declined everything they tried to buy, and I was not liable for anything they attempted charge with it, not even any overdrafts or refused transaction fees. Go Wells Fargo! But...they hooked me up with a business partner identity theft / credit report monitoring outfit, that does the due diligence for a monthly fee! Boo Wells Fargo! But since I already have a service like this that costs me $15 a month, and since they were offering $10 a month with the first month for 99 cents, I decided to try them out. That was two weeks ago. Today I am paying my bills, and in updating my Quicken, I found a $1.00 credit card charge from "TLG*IDPROT14356815AUG 877-8168243 CT" that posted Friday, when I know I didn't buy anything for a dollar even this whole week. I googled the phone number part and got nothing, so I clicked through to dispute the charge. Then I got the idea to re-google it with two hyphens, and get this. Boo Google, and boo Trilegiant! Moral: Make sure you don't look like the danger people are paying you to protect them from. But I've already said that about the cemetery guards in the last Indiana Jones film.

3:39 am	Even Greater Wisdom For All The Internet Ages It has now come to me that my earlier insight has a corollary, that I should be mindful of the mood I am in when I read things I might feel propelled to reply to. And a corollary to the corollary: this sort of honest look at the self and acknowledgment of fault that I seem to expect of others probably isn't any more pleasant for them, and other than a few people who might get it because it never occurred to them before I enunciated it, I can't expect that my rebuke is going to make them happier to embrace it.

Are there any issues that are so important to you that you cannot be friends with someone who holds a contrary opinion? View 981 Answers I've come close with a friend who was taking a a repugnant position but then either let on that he wasn't serious or decided to pretend the same. I suspect some friends of mine I haven't heard from in a while may have begun avoiding me based on my political positions, though they haven't said. (Comment on this)

1:56 am	I've Got the Death Penalty on Twelve Systems ...and four LJs.; maybe more, I'm not sure how to check. This time it was over WATCHMEN. selenite joins the proud throng of wickedthought, evildrganymede, and pyat in ceasing to welcome my replies at their livejournals. Unlike pyat, who had the class to silently turn me off and go back to enjoying his more supportive acquaintances, my fellow Texan selenite did me a drive-by banning, getting the last word off three times before putting the period on our previously civil discussion. Ah, good times. (4 Comments |Comment on this)
