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.

Missing link found between brain, immune system – with major disease implications

UNIVERSITY OF VIRGINIA HEALTH SYSTEM

– Vessels directly connecting brain, lymphatic system exist despite decades of doctrine that they don’t
– Finding may have substantial implications for major neurological diseases
– Game-changing discovery opens new areas of research, transforms existing ones
– Major gap in understanding of the human body revealed
– ‘They’ll have to change the textbooks’

CHARLOTTESVILLE, Va., June 1, 2015 – In a stunning discovery that overturns decades of textbook teaching, researchers at the University of Virginia School of Medicine have determined that the brain is directly connected to the immune system by vessels previously thought not to exist. That such vessels could have escaped detection when the lymphatic system has been so thoroughly mapped throughout the body is surprising on its own, but the true significance of the discovery lies in the effects it could have on the study and treatment of neurological diseases ranging from autism to Alzheimer’s disease to multiple sclerosis.

New Discovery in Human Body

Kevin Lee, PhD, chairman of the UVA Department of Neuroscience, described his reaction to the discovery by Kipnis’ lab: “The first time these guys showed me the basic result, I just said one sentence: ‘They’ll have to change the textbooks.’ There has never been a lymphatic system for the central nervous system, and it was very clear from that first singular observation – and they’ve done many studies since then to bolster the finding – that it will fundamentally change the way people look at the central nervous system’s relationship with the immune system.”

Even Kipnis was skeptical initially. “I really did not believe there are structures in the body that we are not aware of. I thought the body was mapped,” he said. “I thought that these discoveries ended somewhere around the middle of the last century. But apparently they have not.”

“Cry for Freedom” music giveaway

Some great motivational quotes from Chris Eubank…

The tune in the background is a beat I made a couple of years ago, “Cry For Freedom“. I think it’s perfect that they picked this one for this video. It’s on my album “Classic Beats Volume 3“, but you can get it here for free: DjSadhu-CryForFreedom.mp3 (right click -> “save target as…”)

LondonReal.tv now using DjSadhu beats

Proud to announce that LondonReal.tv is now using my beats for their trailers and episodes.

My music is available on BandCamp and GooglePlay. Here are some of their new trailers:
