  1. Re:Maybe Autism isn't abnomral? on CDC Reports 1 In 88 Children Now Affected With Autism In the US · · Score: 5, Informative

    There's a pretty active debate over how to classify it, and how it relates to "normal" functioning, and some of the major theories do at least hint in the direction that the picture of "normality" is complex.

    One model, which has a clearer division, is that there is a specific etiology, which would make "autism" a more conventional "disease" in a sense, in that some people have it and some don't, and there is a known cause.

    However another major model views the "autism spectrum" as something like the tail of a normal Bell-curve distribution for some cluster of traits. In that case, the dividing line between "normal" and "not normal" becomes a more subjective one having to do with how far in the tails you decide to put a cutoff, which probably involves some judgment of ability to function in society (which in turn depends on the society).

    Other models think that we're conflating several etiologies in this big basket, and that some may be discrete diseases while others are tail-of-a-Bell-curve traits.

  9. Re:Dang it. I'm confused. Remind me again... on Supreme Court Limits Patents Based On Laws of Nature · · Score: 1

    The the opinion discusses that, since it's at the heart of the case. The key issue is that natural processes and abstract ideas aren't patentable, but processes or methods applying them may be, if the application involves something significant in its own right. However they found that in this case the application consisted of basically the natural law, combined with instructions to doctors to use the natural law, which was too trivial an application. As the opinion argues:

    ...to transform an unpatentable law of nature into a patent-eligible application of such a law, one must do more than simply state the law of nature while adding the words “apply it.”

    In this specific case:

    Prometheus’ patents set forth laws of nature --- namely, relationships between concentrations of certain metabolites in the blood and the likelihood that a dosage of a thiopurine drug will prove ineffective or cause harm. [...] While it takes a human action (the administration of a thiopurine drug) to trigger a manifestation of this relation in a particular person, the relation itself exists in principle apart from any human action. The relation is a consequence of the ways in which thiopurine compounds are metabolized by the body --- entirely natural processes. And so a patent that simply describes that relation sets forth a natural law.

    The question before us is whether the claims do significantly more than simply describe these natural relations. To put the matter more precisely, do the patent claims add enough to their statements of the correlations to allow the processes they describe to qualify as patent-eligible processes that apply natural laws? We believe that the answer to this question is no.

    Incidentally, the opinion is actually pretty clear and seems to "get" it, at least on this particular point. Contrary to usual practice when reading patent-related court opinions, I did not either: 1) fall asleep while doing so; or 2) feel the need to yell at the monitor.

    I think it depends a lot on the area. We're closer to replacing programming classes with online courses than we are to replacing, say, civil-engineering degrees; at least for the near-term future, nobody is going to license you to work on a bridge if you don't have a college degree, no matter how many online videos you've watched. Part of the reason imo is that it's easier to demonstrate competence in programming, e.g. by having a "Github resume" of non-trivial projects you've worked on in your spare time.

  15. Re:What's revolutionary? on DARPA Director Leaves Pentagon For Google · · Score: 4, Informative

    There are various places you can live on the axes of basic versus applied research, though. DARPA traditionally spent a larger proportion of its budget on basic research than it does today; nowadays the vast majority of DARPA projects intend practical outcomes in the 3-5-year timeframe, often pairing universities doing near-term applied research with companies like Lockheed who're simultaneously implementing it, and expected to exercise considerable pressure on the university partners to focus their research on the near-term "deliverable". Traditionally, that was part of the DARPA budget, while blue-skies research, often in the form of block grants to e.g. a physics or CS research group, was another part of it. The relative percentages have shifted a lot towards the former.

    Some of the justification is that the NSF is supposed to fund basic research, while DARPA is supposed to fund things of near-term practical use to the military. That makes some sense conceptually, but a shift in DARPA priorities without a reallocation in funds between the NSF and DARPA means that in effect science/engineering research funding is being cut in favor of something that leans closer to military R&D.

  17. Re:would be interesting to mine their data on Gamers Outdo Computers At DNA Sequence Alignments · · Score: 1

    I don't think that's universally true; for example, computers are much better at characterizing integer sequences than (almost?) any human is, because humans are just not that good at integer sequences, especially those with any sort of non-trivial mathematical relationship underpinning them. Humans are good at a fairly specific set of pattern-recognition tasks, like object recognition in images. Even there, they vary surprisingly strongly by the specific nature of the task; for example, humans are much better at recognizing faces than just about anything else--- and this ability is so specialized that humans generally can't process upside-down faces nearly as well.

  18. Re:would be interesting to mine their data on Gamers Outdo Computers At DNA Sequence Alignments · · Score: 3, Insightful

    That's true; a legitimate hypothesis is that this task involves very difficult skills that humans are naturally adept at, like object recognition in images does. My guess is that aligning DNA sequences is not as strong an example of one of those kinds of problems as object recognition, in particular because it doesn't involve the large amount of general knowledge about the world that we bring to bear when interpreting scenes; aligning sequences is more of a "formal" problem, than recognizing what constitutes a "chair". But I'll admit I could be wrong. One way to find out would be to try to see how much can be mined from the data. ;-)

  19. would be interesting to mine their data on Gamers Outdo Computers At DNA Sequence Alignments · · Score: 5, Interesting

    I'm highly skeptical that these gamers are really using some un-automatable human-only deep skills, especially since they aren't exactly extensively trained in this game, not to the level of, say, good Go players. So the interesting question to me is not that they beat current algorithms, but whether data mining these hundreds of thousands of alignments can tell us something about how they're doing it. My guess is that there are some heuristics that can be mined from this data that would massively speed up search.

    That's a more general point about how these stories are always pushed, though, sometimes by media, sometimes by the researchers themselves. Imo the most exciting thing about successful uses of "human computation" isn't that we can harness people to do things, but that we can gain some large data sets that will make it so we don't have to get people to do them anymore. Or at least, that should be the baseline, imo: that humans can beat some hand-crafted algorithm is one thing, but can they beat machine-learned algorithms trained on those humans' own gameplay logs?

    That was also my reaction on reading that--- why should we assume that the next great innovation in gaming will necessarily involve "a lot more computing power"? It's possible that there exist such innovations, but I'm also pretty confident that we haven't exploited the gaming possibilities of current hardware, or even of last-gen hardware. Heck, going back further, I don't think the SNES era actually explored all the gaming possibilities that one could've explored on an SNES; the market moved on so some avenues never got explored.
