They say that there could be an infinite amount of data transferred with this method, but I find that very hard to believe. Surely there is an upper limit

It appeared to me the limit is only in our hardware and the sensitivity they can get out of it.

Google's 'brain simulator': 16,000 computers to identify a cat

Quote:
Inside Google's secretive X laboratory, known for inventing self-driving cars and augmented reality glasses, a small group of researchers began working several years ago on a simulation of the human brain.
There Google scientists created one of the largest neural networks for machine learning by connecting 16,000 computer processors, which they turned loose on the internet to learn on its own.
Presented with 10 million digital images found in YouTube videos, what did Google's brain do? What millions of humans do with YouTube: looked for cats.

The neural network taught itself to recognise cats, which is actually no frivolous activity. This week the researchers will present the results of their work at a conference in Edinburgh, Scotland.
The Google scientists and programmers will note that while it is hardly news that the internet is full of cat videos, the simulation nevertheless surprised them. It performed far better than any previous effort by roughly doubling its accuracy in recognising objects in a challenging list of 20,000 distinct items.

Much, much more info in the article. Heres another interesting quote though:
Quote:
"We never told it during the training, 'This is a cat,' " said Dr. Dean, who originally helped Google design the software that lets it easily break programs into many tasks that can be computed simultaneously. "It basically invented the concept of a cat. We probably have other ones that are side views of cats."

This is what it came up with for a human face. Honest to god this looks eerily similar to one of my good friends

What do I think?
I think it's an entertaining TV show.

But of course.
All they have is the events as it was recorded in their memories, so they make a show out of it.
Brilliant.

The Higgs boson announcement is all over the news today. They definitely discovered a new large boson, and it looks very very similar to the predicted Higgs particle.

And in cosmological news, a filament of dark matter has been "observed", and I use that term lightly.
http://www.nature.com/news/dark-matt...vealed-1.10951





This is the future of computer-human interaction
http://www.kurzweilai.net/robot-avat...-thought-alone
Quote:
For the first time, a person lying in an fMRI machine has controlled a robot hundreds of kilometers away using thought alone.

."The ultimate goal is to create a surrogate, like in Avatar, although that's a long way off yet," says Abderrahmane Kheddar, director of the joint robotics laboratory at the National Institute of Advanced Industrial Science and Technology in Tsukuba, Japan.

Teleoperated robots, those that can be remotely controlled by a human, have been around for decades. Kheddar and his colleagues are going a step further. "True embodiment goes far beyond classical telepresence, by making you feel that the thing you are embodying is part of you," says Kheddar. "This is the feeling we want to reach."

To attempt this feat, researchers with the international Virtual Embodiment and Robotic Re-embodiment project used fMRI to scan the brain of university student Tirosh Shapira as he imagined moving different parts of his body. He attempted to direct a virtual avatar by thinking of moving his left or right hand or his legs.

The scanner works by measuring changes in blood flow to the brain's primary motor cortex, and using this the team was able to create an algorithm that could distinguish between each thought of movement (see diagram). The commands were then sent via an internet connection to a small robot at the Béziers Technology Institute in France.

The set-up allowed Shapira to control the robot in near real time with his thoughts, while a camera on the robot's head allowed him to see from the robot's perspective. When he thought of moving his left or right hand, the robot moved 30 degrees to the left or right. Imagining moving his legs made the robot walk forward.

To test the extent of his feelings of embodiment, the researchers also surprised him with a mirror (see "On the inside, looking out***8220. "I really felt like I was there," Shapira says. "At one point the connection failed. One of the researchers picked the robot up to see what the problem was and I was like, 'Oi, put me down!'"

The brain is very easily fooled into incorporating an external entity as its own. Over a decade ago, psychologists discovered that they could convince people that a rubber hand was their own just by putting it on a table in front of them and stroking it in the same way as their real hand. "We're looking at what kinds of sensory illusions we can incorporate at the next stage to increase this sense of embodiment," says Kheddar. One such illusion might involve stimulating muscles to create the sensation of movement (see "Feeling is believing***8220.

The researchers are also fine-tuning their algorithm to look for patterns of brain activity, rather than simply areas that are active. This will allow each thought process to control a greater range of movements. "For example, you could think of moving your fingers at different speeds and we could correspond that with different speeds of walking or turning," says Cohen, who presented the results of the embodiment trials at BioRob 2012 in Rome, Italy, last week.

So far, only healthy people have embodied the surrogate. Next, the researchers hope to collaborate with groups such as Adrian Owen's at the University of Western Ontario in Canada to test their surrogate on people who are paralyzed or locked in.

"I think it is very impressive and in the broadest sense reflects where it is that we are trying to get to in enabling communication in patients who are deemed to be locked in or even vegetative," says Owen. He cautions, though, that there is a long way to go before the technology is able to provide long-term help for patients.

Electroencephalogram (EEG) technology, which uses electrodes attached to the scalp to record electrical activity in the brain, is likely to prove more practical than fMRI, he says, since it is cheaper and more comfortable to use for extended periods of time. Although EEG has been used to control robots, the readings are not yet as clear as those from fMRI. Nevertheless, this demonstration is "an interesting glimpse of what might be possible in the future," Owen says.

This is pretty exciting. To sum up the article: Researchers have identified what causes loss of plasticity in the brain and are studying drugs and treatments to re-open what they call the "critical period" when our brain is incredibly plastic and open to learning new things. If they are correct (and there is evidence to suggest they are), then an adult could learn an instrument or new language just as easily as a child.

Cowmoo, have you read American Prometheus? I just started it. It's long, but so far very interesting. From what I've read, to call Oppenheimer remarkable would be an understatement.



Since you're a fan of Feynman, you might find this interesting, too:

Would that give us some childlike qualities, too? I thought that part of the reason children learn so quickly is because their frame of reference is not as clearly defined. It's the same reason why you will try to find a mathematical answer to any problem that uses numbers, while a child might see it differently. In other words, kids learn faster because they know less.

Kind of like this:

Ok, what the fvck. That problem is pissing me off. I need to get some actual work done but I'm going to revisit it in an hour or two.

Oh lawd.

I know the answer!

I seriously stumped my father for a pretty decent amount of time.
