Comment Re:Not one example? (Score 2) 50

I'm a professional neuroscientist that specializes in vision research with a computational bent. They used all the main stream, state of the art, openly available object recognition algorithms currently in use. Computer vision is a huge market, with many applications, from the DoD to self-driving cars to image-based searches. I doubt some 5-figure prize is going to out perform the best algorithms several distinct industries and academia have managed to create while being funded to the tune of over a billion a year for the last 10 years or so.

These are serious researchers. If you think you think you can get any type of computer vision that significantly outperforms humans on this type of task, there is a unicorn startup and multiple ultra-high profile publications awaiting you.

And just FYI based on your further post: they used two types of convolutional neural nets (see Methods: Model Versions and Parameters).

With regard to that, I'd highly recommend Fatal Passage by Ken McGoogan, which is a biography of arctic explorer John Rae, who conducted the search for the Franklin expedition (and probably could have rescued them if things had worked out just a little bit differently) and discovered the final link in the northwest passage that Amundsen used 50 years later.

Comment Re:So which agencies' backdoors are in there? (Score 1) 135

My experience tells me absolutely nothing about whether Canada was being diligent in border screening.

In every single case I crossed a border as a minor it was with free will and full paperwork, so I can't say if the screening was diligent in a way that would uncover a coercive crossing situation.

It also doesn't tell me anything about their screening criteria. Making too many type 2 errors, like I experienced with my grandparents, means that resources are not being effectively directed. And that has costs as well, since after that experience neither my family nor I returned to Canada until after I was an adult.

We had proper documentation (notarized permission letter, notarized copy of my birth certificate, passport)... The reason I say it's a Canadian neurosis (albeit semi-seriously) is that I made many other (25 or so) border crossings as a minor without parental accompaniment (many more with one parent), and never had an issue anywhere else (including Mexico, France, Italy, England, Austria, US, Switzerland, Cayman Islands).

I made at least 25 border crossings (mostly foreign-foreign) while a minor and not under the care of my parents or with a cousin who was not under the care of their parents (including a solo one to Mexico to meet up with some family friends when I was 10, although IIRC that was pretty paperwork heavy with the airline)... Canada was the only time there was any trouble.

Many years ago, when I was 6 or 7, my grandparents drove me up to Prince Edward Island for a vacation. Getting through the border into Canada took about 45 minutes, with my grandparents getting grilled and the agents asking me about a dozen times whether I wanted to be with them and whether my parents knew where I was etc etc.. Getting back into the US took about 2 minutes. It seems like it's a Canadian neurosis.

Both of the effects you describe are because the fovea has thicker ganglion cell density than non-foveal regions, which can induce a color bias over the several central degrees of your visual field. It's not 100% clear to me whether the GP is describing a visual hemifield effect, or an eye based effect (in the case of hemifields, each eye sends half its signal to each visual cortex)... but either way, it doesn't to me sound like a fovea-based bias.

(To clarify, by physical thing, I meant something that is both involuntarily induced, and non-constant)

I am a neuroscientist, mainly in vision, not an ophthalmologist.. but I have sat in on quite a bit of ophthalmology, done orbital dissections etc etc.. Very few physical things (ie. pressure based) can effect color perception. The main one is that you have something (either tumor, or spurious bone growth) that's pinching or entrapping your optic nerve (basically like carpel tunnel). If the same were happening to me, I'd make sure to get referred to an ophthalmology department at a research hospital and get a CAT scan to make sure nothing is growing behind the orbit.

Comment Re:Not a computing element (Score 5, Informative) 183

That's mentioned in the IEEE Spectrum article (which by the way is about the most clearly written article on an early prototype technology that I've ever read).
The problems are:
-Too high voltage; can be mitigated by better geometry (probably).
-Insufficient simulations at present for improving the geometry, with the caveat that getting better performance (voltage-wise) might compromise durability.
-Because of the above, they don't have a good set of design rules to produce an integrated circuit. They're hopeful about this step, since the technique uses well established CMOS technology and there are many tools available.

Their next targets are things like gyroscopes and accelerometers. I'd say on the whole this strikes me as realistic and non-sensational. But if anybody knows better, I'd like to hear why.

Comment citation puffery (Score 1) 231

This is no different from trying to come up with ways of measuring scholars' intellectual impact using citation metrics, like the h-factor or the many recent successors to it, which try to repair the weaknesses in a fatally flawed idea. It makes no distinction between positive and negative citation, and it ignores the raw fact of historical precedence, while preserving every historical bias a culture may have.

The most influential people in world history, at least the very top-tier, isn't particularly debatable, but yet this list failed to capture it. In alphabetical order (and assuming they all existed):

Aristotle
Buddha
Confucius
Homer
Jesus
Lao Tzu
Muhammad
Plato
Ved Vyasa

Then there's the next tier, which include people like Al-Hazan, Alexander, Augustine, Einstein, Genghis, Hammurabi, Imhotep, Newton, Linnaeus, Peter (of Russia), Shakespeare, Suleiman, Zeami Motokiyo etc etc, since I'm sure the further I try to extend the list, the more it would converge with my cultural history.

While unsupervised algorithms can often find interesting things in high-dimensional data, they aren't interpret-able without some expert knowledge.. and if you don't have the 9 entries I mentioned above in your top 20 at least, you can toss the method.
