Submission + - Deep neural networks are easily fooled: Is this Snowcrash for AI? (youtube.com) 1

anguyen8 writes: Deep neural networks (DNNs) trained with Deep Learning have recently produced mind-blowing results in a variety of pattern-recognition tasks, most notably speech recognition, language translation, and recognizing objects in images, where they now perform at near-human levels. But do they see the same way we do?

Nope. Researchers recently found that it is easy to produce images that are completely unrecognizable to humans, but that DNNs classify with near-certainty as everyday objects. For example, DNNs look at TV static and declare with 99.99% confidence it is a school bus. An evolutionary algorithm produced the synthetic images by generating pictures and selecting for those that a DNN believed to be an object (i.e. “survival of the school-bus-iest”). The resulting computer-generated images look like modern, abstract art. The pictures also help reveal what DNNs learn to care about when recognizing objects (e.g. a school bus is alternating yellow and black lines, but does not need to have a windshield or wheels), shedding light into the inner workings of these DNN black boxes.

Submission + - Chinese Hackers Infiltrate US Army Database, Compromise Safety Of Thousands Of D (ibtimes.com) 1

coolnumbr12 writes: Chinese hackers have infiltrated a sensitive U.S. Army database that contains information about the vulnerabilities of thousands of dams located throughout the United States. TheU.S. Army Corps of Engineers’ National Inventory of Dams (NID) has raised concerns that information gathered in the hack attack could help China carry out a cyberattack on the national electrical power grid.

Submission + - Police unsure which twin to charge in sexual assaults

An anonymous reader writes: In a real life Prisoner's Dilemma taking place in the French city of Marseille, twin brothers have been arrested for a string of sexual assaults. While say they are sure that one of them committed the crimes (corroborated by a standard DNA test), police were told that it would cost upwards of €1m euros (£850,000, $1.3m USD) to distinguish between them using DNA evidence.

Submission + - Crowdsourced evolution of 3D printable objects (endlessforms.com)

JimmyQS writes: "The Cornell Creative Machines Lab, which brought us chatbots debating God and unicorns, has developed Endlessforms.com, a site using evolutionary algorithms and crowdsourcing to design objects that can be 3D printed in materials such as silver, steel or silicone. MIT's Technology Review says "The rules EndlessForms uses to generate objects and their variants resemble those of developmental biology—the study of how DNA instructions unfold to create an entire living organism. The technology is 'very impressive,' says Neri Oxman, director of the MIT Media Lab's Mediated Matter research group. She believes the user-friendliness of the evolutionary approach could help drive the broader adoption of 3-D printing technologies, similar to how easy-to-use image editors fueled the growth of digital photography and graphic manipulation. Oxman [notes] that this could ultimately have an impact on design similar to the impact that blogs and social media have had on journalism, opening the field to the general public." The New Scientist has a quick video tour and describes how the same technology can evolve complex, artificially intelligent brains and bodies for robots that can eventually be 3D printed."

Hello. What makes the HyperNEAT approach a breakthrough is its use of a generative encoding based on concepts from developmental biology. Please see my comment one ply deeper in this thread for more information. I encourage you to check out the HyperNEAT publications in order to see why this is very powerful and new technology.

Hello- I posted this in reply to another comment, but it is relevant to this thread as well. The HyperNEAT technology is actually cutting-edge, and represents a major innovation versus previous neuroevolution techniques. One major thing that differentiates it from previous evolution of ANNs is that HyperNEAT is based on concepts from developmental biology. Specifically, it evolves compositions of geometric coordinate frames that are abstractions of the diffusing chemical gradients of developing embryos. These concepts enable the evolution of regular patterns in neural wiring that have not been seen before in neuroevolution (see, for example, the pictures of evolved brains in my dissertation, which is available at my website: www.msu.edu/~jclune). The ability to generate regular wiring patterns enables evolution to search in a small search space of short genomes, yet produce functioning brains with millions or more connections. Of course, this article was written for the popular press, so they did not have the ability to get to this level of detail. For those of you that already know a lot about evolutionary computations and neural nets, I encourage you to read the publications about HyperNEAT, either at my website or at those of other researchers using the technology (e.g., the University of Central Florida). I think you'll then be impressed by the breakthroughs in HyperNEAT. You are correct that evolutionary computation itself has been around for a while. But the science described in this article is pushing that technology further. Best, Jeff Clune Postdoctoral Scientist Michigan State University
