Hell is Other People "Fight the ghosts of those that have come before by moving in two dimensions and shooting missiles. The fiercer you fight, the harder it shall be for those that come after. How much past can you cope with before you are overwhelmed?"

Two AI Pioneers. Two Bizarre Suicides. Wired's David Kushner examines the work of two young, competitive AI researchers, and the eerie circumstances of their deaths.

"How would it be, for example, to relate to a machine that is as intelligent as your spouse?"

Impressed and alarmed by advances in artificial intelligence, a group of computer scientists is debating whether there should be limits on research that might lead to loss of human control over computer-based systems that carry a growing share of society’s workload, from waging war to chatting with customers on the phone. From the NYT: Scientists Worry Machines May Outsmart Man.

a pink sliver of rat brain sat in a beaker

The simulated brain - "The scientists behind Blue Brain hope to have a virtual human brain functioning in ten years... Dr. Markram began by collecting detailed information about the rat's NCC, down to the level of genes, proteins, molecules and the electrical signals that connect one neuron to another. These complex relationships were then turned into millions of equations, written in software. He then recorded real-world data -- the strength and path of each electrical signal -- directly from rat brains to test the accuracy of the software." Is it possible to digitally simulate a brain accurately? Can it only be analog? And are there quantum effects to be considered? (previously 1 2 3 4) + some other AI/brain robot projects:

Blue Brain is controversial, and its success is far from assured. Christof Koch of the California Institute of Technology, a scientist who studies consciousness, says the Swiss project provides vital data about how part of the brain works. But he says that Dr. Markram's approach is still missing algorithms, the biological programming that yields higher-level functions... Despite the challenges, the push to understand, replicate and even re-enact higher behaviors in the brain has become one of the hottest areas of neuroscience. With the help of a $4.9 million grant from the U.S. Department of Defense, IBM is working on a separate project with five U.S. universities to build a tiny, low-power microchip that simulates the behavior of one million neurons and ten billion synapses. The goal, says IBM, is to develop brainy computers that can better predict the behavior of complex systems, such as weather or the financial markets. The Chinese government has provided about $1.5 million to a team at Xiamen University to create artificial-brain robots with microcircuits that evolve, learn and adapt to real-world situations. Similarly, Jeff Krichmar and colleagues at the University of California, Irvine, Calif., have built an artificial-brain robot that learns to sharpen its visual perception when moving around in a lab environment, another form of emergent behavior, a form of spontaneous self-organization. And researchers at Sensopac, a project backed by a grant of €6.7 million ($9.3 million) from the European Union, have built part of an artificial mouse brain.

What Not To Sing

booksherpa — Tue, 07 Jul 2009 18:33:30 -0800

I understand that MeFites don't really do American Idol, but if you're the rare one who does, then you will probably appreciate the combination of fandom and geekery that produced What Not To Sing. They look at reviews of AI performances from all over the web, and distill them to provide numerical and star ratings for each AI performance. Every one. EVER. They have a listing of the top and bottom 40 performances across all 8 seasons, which makes for interesting YouTube searching. If you're curious about all performances of Michael Jackson songs on the show or just wish to confirm that Sanjaya sucked, they can help with that as well. The feature currently amusing me is this season's Camp Should-A-Been, where they judge contestants solely on performance rating, with the lowest rated performer leaving.

Electronic Evolution: Research Show Robots Forming Human-like Societies

Within fifty generations of this electronic evolution, co-operative societies of robots had formed - helping each other to find food and avoid poison. Even more amazing is the emergence of cheats and martyrs. Transistorized traitors emerged which wrongly identified poison zone as food, luring their trusting brethren to their doom before scooting off to silently charge in a food zone - presumably while using a mechanical claw to twirl a silicon carving of a handlebar moustache.

IBM Research is planning on working on taking artificial intelligence beyond master-level Chess (previously), and on to question answering with a computing system that has been in development for the past two years. Named "Watson," after the I.B.M. founder, Thomas J. Watson Sr., the system will challenge human contestants at Jeopardy (previously). Watson's success depends as much on its ability to understand and respond to the subtleties of human language as it does on the extent of its knowledge database. Don't worry, Alex Trebek knows what's in store. (via)

80 Million Tiny Images

Currently computers have difficult recognizing objects in images. While practical solutions exist for a few simple classes such as human faces or cars, the more general problem of recognizing all different classes of objects in the world (e.g. guitars, bottles, telephones) remains unsolved. Computer Vision researchers are currently investigating methods that can recognize and localize thousands of different object categories in complex scenes. A key component of these algorithms is the data used to train the computers' model of each object. Current approaches use collections of images gathered by hand. Our research explores how the billions of images available on the Internet can be used to train models for object recognition. With overwhelming amounts of data, many problems can be tackled with simple algorithms. We gathered from the web 79 million images. We are using this massive dataset to train a computer to recognize objects within an image and to understand the scenes depicted in photographs. You can help... get better training data for computer vision algorithms by labeling some of the images.

Deep Geek: Understanding Memristors

NortonDC — Sun, 07 Dec 2008 19:54:57 -0800

The coming memristor revolution in electronics and how it works. The newly created memristor, only the fourth fundamental fundamental type of passive circuit element, has the promise of computing advances both prosaic (faster, cheaper and "bigger" flash drives) and momentous (relatively effortless mimicry of brain cells and their activity). This is the story of the memristor's genesis, told by R. Stanley Williams, the leader of the team that created the device. Being deeply geeky myself, I've read about memristors before, but reading this article and sidebar finally let me understand how the memristor works and what happens inside it. And that felt pretty damn good. The article is fantastic, but it does leave one key connection unmade. To create a practical memristor, the team "needed [a] mechanism by which we could change the effective spacing between two wires in our crossbar by 0.3 nm. If we could do that, we would have the 1000:1 [variation in conductivity] we needed... Where would we find a material that could change its physical dimensions like that?" They did create a way to vary that spacing, in a controllable, repeatable, and extremely fast-acting manner, but Williams doesn't directly explain how the internal actions of the switching layer meet that requirement. The payoff for that setup is missing. When electrical current pushes the conductive impurities in the layer of titanium dioxide toward the other wire, the conductive portion of the layer grows toward the other wire, and the insulating portion of the layer thins. That thinning is described, but the article never tells the reader that expansion of the conductive layer is that long-sought means of moving the wires. If you read the article and made that connection before I described it, then you might have felt as smug about it as I did. Williams gets to feel more smug.

New AI "Elbot" Scores 20% On Turing Test!

goodhelp — Mon, 13 Oct 2008 16:07:10 -0800

Think you can stump the Elbot? Give it a try. Maybe your interaction will enable it to "learn" an extra 10% more to pass the 30% threshold of the Turing Test. The test is to fool a panel of people who talk with AI entities via text and guess if it's a real person or a robot.Mr Smarty Pants where are you?

AI - sooner rather than later?

Sparx — Mon, 24 Sep 2007 13:32:28 -0800

Dr. Ben Goertzel is an interesting guy. Having previously tried to create an AI based on internet distribution he refined his approach. High level elaborations on his developing thinking here, here and here (arranged chronologically). He gave a talk to Google about it recently (video) (related text), while mentioning why he thought Google isn't in the AI business. Here's a (low quality, sorry) vid of his system's virtual learning in action. Research finances were always a problem - could this be a solution?

Introduced to Western culture by the Beatles in their single Norwegian Wood, the sitar has featured prominently in North Indian classical music for centuries. Princeton-based computer scientist Ajay Kapur updates the instrument with his ESitar, an audio and video controller that uses gesture input (PDF) and machine learning algorithms to facilitate joining the computer with Ajay in his sitar performance. Undergraduate engineering students at the University of Pennsylvania work from the other direction, building RAVI-bot, an award-winning, self-playing robotic sitar (YouTube) programmed to generate music from classical Raga scales and melodies all on its own. For those in the Philadelphia area, be sure to check out a live performance of RAVI-bot at the local Klein Art Gallery.

Jeff Hawkins unleashes his brain: Numenta's new AI platform

grumblebee — Wed, 04 Apr 2007 13:35:42 -0800

Jeff Hawkins, co-founder of Palm and Handspring, has started a new company, called Numenta, to test his controversial theory of intelligence. Whether you find his theory plausible or not, his book, "On Intelligence" is fascinating. Numenta is attempting to build A.I.s using Hawkins' theory as a backbone. They've developed a software engine and a Python-based API, which they've made public (as free downloads), so that hackers can start playing. They've also released manuals, a whitepaper (pdf) and videos [1] [2]. (At about 30:18 into the first video, Hawkins demonstrates, with screenshots, the first app which uses his system.)
