Research Blog: Inceptionism: Going Deeper into Neural Networks

Really cool article, basically google trained a simple neural network to identify images. But they wanted to know what the neural network was actually recognizing as the object. So they initially gave it a blank canvas and asked it to fill it with what it thought a dumbbell was, and it produced some images. Then they took other images unrelated to what it was trained to see, and told it to find those things in the images and those trippy pictures are what it's producing as output. It produces some really mind bending art.
its crazy how psychedelic those images are. i'd even go so far as to say that those feedback loops they're making are decent models of what is going on inside the human brain while on psychedelics.

I wonder how easy it would be to camouflage things against that type of pattern recognition. And could you teach the computer to recognize it through the camo, or would you cause a lot of false positives?

Shit's creepy.

The creature that painted those fits neatly into HG Wells' notion of "intelligences vast, cool, and unsympathetic". It sees with a thousand eyes and fashions reality to its own alien, unknowable design. Once it wakens to our existence it will open its hundred mouths and sing the song that will end the world.

"But even though these are very useful tools based on well-known mathematical methods, we actually understand surprisingly little of why certain models work and others don?t"

If there's one thing science fiction has taught me it's do not trust any sort of artificial intelligence you don't know everything about, as well as methods to control it. *tinfoilhat*

Now they just need to get to work on those hoverboards...

The British-made Malloy Hoverbike, which burst onto the scene last year as a Kickstarter project, is being picked up by the US Department of Defense. The DoD is looking at the hoverbike as a multiple-role transport craft: it can transport soldiers over difficult terrain, but it can also operate in drone mode, providing logistical or surveillance support.

Huh. I never knew there was such a thing as an albino plant.

I'd say "well, it makes sense" but it actually doesn't!

Witchery.

I read an article on Albino Redwoods some time ago. Park rangers try to keep them secret because people like to take souvenirs.

That makes sense, people are assholes because they were made in someone's image. An asshole.

Christina Smolke, a bioengineering professor at Stanford University, points out that while we now know the genes that enable the entire opiate production process in poppies, it doesn't mean that making yeast mimic that process will be easy. "If you have to engineer yeast to make about twenty enzymes it doesn't normally make, it's really complex," she says. "This work is certainly a piece of the puzzle, but we still need a lot more pieces."

Smolke's lab has recently replicated some of the opiate-producing steps in yeast and has been aiming to not only to have the yeast produce the opiates, but also further refine the chemicals into purer forms like hydrocodone that pharmaceutical companies need-essentially making the fermentation vat into a pharmaceutical factory. But scientists like Smolke and Graham can't forge ahead blindly in their laboratory goals: When they finally manage to make yeast produce opiates, this may open new legal questions regarding the risk of people procuring the genetically modified yeast and homebrewing the opiates themselves.

Obviously they just needed to make Corn that produces Opiates instead, since Iowa's agriculture lobby can apparently push anything through they want.

So Lexus showed off their hoverboard in that viral video:



It's actually a pet project to promote a their SLIDE development team. But it actually uses something called "Quantum Locking", which uses superconductors to lock things in space via the meissner field. The video is a few years old and they had a TED talk around that time. There are real applications in manufacturing and stuff but fuck that, make me a hoverboard.

Isn't this basically the same thing as that kickstarter one that beat them by a year or so? Like you need a metal sheet under the skate park and it's not anywhere near an actual hoverboard?

The Hendo was a straight electromagnetic hoverboard afaik. But yeah the Lexus board uses a magnetic surface too, but like that quantum locking video shows it can tilt and it would stay tilted unless the user reoriented it. Lexus made the board just to help promote their SLIDE project, they're not going to market with it.

Oh, that's actually cool. Still not a legit 'hoverboard' per se but the orientation fix thing is very cool.
