In breaking news, Andy and Dave discuss Google’s decision not to renew the contract for Project Maven, as well as their AI Principles; the Royal Australian Air Force holds a biennial Air Power Conference with a theme of AI and cyber; the Defense Innovation Unit Experimental (DIUx) releases its 2017 annual report; China holds a Defense Conference on AI in cybersecurity, and NVidia’s new Xavier chip packs $10k worth of power into a $1299 box. Next, Andy and Dave discuss a benevolent application of adversarial attack methods, with a “privacy filter” for photos that are designed to stop AI face detection (reducing detection from nearly 100 percent to 0.5 percent). MIT used AI in the development of nanoparticles, training neural nets to “learn” how a nanoparticle’s structure affects its behavior. Then the remaining topics dip deep into the philosophical realm, starting with a discussion on empiricism and the limits of gradient descent, and how philosophical concepts of empiricist induction compare with critical rationalism. Next, the topic of a potential AI Winter continues to percolate with a viral blog from Piekniewski, leading into a paper from Berkley/MIT that discovers a 4-15% reduction in accuracy for CIFAR-10 classifiers on a new set of similar training images (bringing into doubt the idea of robustness of these systems). Andy shares a possibly groundbreaker paper on “graph networks,” that provides a new conceptual framework for thinking about machine learning. And finally, Andy and Dave close with some media selections, including Blood Music by Greg Bear and Swarm by Frank Schatzing.
