Google’s A.I. now has Artificial Imagination

Google has modified its image recognition neural net with a feedback loop.. and it now “dreams up” images of its own, even from nothing…

But if the neural network is tasked with finding a more complex feature – such as animals – in an image, it ends up generating a much more disturbing hallucination:

Ultimately, the software can even run on an image which is nothing more than random noise, generating features that are entirely of its own imagination.

“One way to visualise what goes on is to turn the network upside down and ask it to enhance an input image in such a way as to elicit a particular interpretation,” they add. “Say you want to know what sort of image would result in ‘banana’. Start with an image full of random noise, then gradually tweak the image towards what the neural net considers a banana.”

The image recognition software has already made it into consumer products. Google’s new photo service, Google Photos, features the option to search images with text: entering “dog”, for instance, will pull out every image Google can find which has a dog in it (and occasionally images with other quadrupedal mammals, as well).

So there you have it: Androids don’t just dream of electric sheep; they also dream of mesmerising, multicoloured landscapes.

Continuous liquid interface production of 3D objects

Solid objects can be printed from liquid resin in mere minutes.

With a trick of chemistry, researchers have sped up, and smoothed, the process of three-dimensional (3D) printing, producing objects in minutes instead of hours.

3D printers typically build one horizontal layer at time. Some do so by depositing droplets of building material as if they were laying tiny bricks. Others create their products by shining ultraviolet rays up into a bath of liquid resin. The light solidifies the resin, and the partial product is pulled upwards one notch to repeat the process for the next layer below. Objects appear to materialize out of the bath, just as the shape-shifting robot in the 1991 science-fiction film Terminator 2 formed out of liquid metal.

A team led by Joseph DeSimone, a chemist at the University of North Carolina at Chapel Hill, has now refined the liquid-resin process to make it go continuously rather than in fits and starts. They made the bottom of the container that holds the resin bath from a material that is permeable to oxygen. Because oxygen inhibits the solidification of resin, it creates a ‘dead zone’ — a layer just tens of microns thick at the bottom of the container — where the resin stays liquid even when ultraviolet rays are shining on it. The solidification reaction happens instead just above the dead zone. Because liquid is always present below the slowly forming object, the researchers can pull it up in a continuous manner, rather than waiting for new liquid resin to flow in.

CERN hopes to make contact with parallel universe?

Oh, really? And what do they hope to find…

Scientists at Large Hadron Collider hope to make contact with PARALLEL UNIVERSE in days

Large-Hadron-Collider-LHC-565315If successful a completely new universe will be revealed – rewriting not only the physics books but the philosophy books too.
It is even possible that gravity from our own universe may ‘leak’ into this parallel universe, scientists at the LHC say.
The experiment is sure to inflame alarmist critics of the LHC, many of whom initially warned the high energy particle collider would spell the end of our universe with the creation a black hole of its own.
