For something that we spend a third of our lives doing (if we’re lucky), sleep is something that we know relatively little about. “Sleep is actually a relatively recent discovery,” says Daniel Gartenberg, a sleep scientist who is currently an assistant adjunct professor in biobehavioral health at Penn State. “Scientists only started looking at sleep...
In this post I will demonstrate SimpleITK, an abstraction layer over the ITK library, to segment/label the white and gray matter from an MRI dataset. I will start with an intro on what SimpleITK is, what it can do, and how to install it. The tutorial will include loading a DICOM file-series, image smoothing/denoising, region-growing…
There is a reason why the porn industry makes billions off the people who like to indulge in the visually appealing and arousing experience of watching porn.
There’s a new automated propaganda machine driving global politics. How it works and what it will mean for the future of democracy.
by Berit Anderson and Brett Horvath
"Targeted advertising allows a campaign to say completely different, possibly conflicting things to different groups. Is that democratic?"
"Cambridge Analytica isn’t the only company that could pull this off -- but it is the most powerful right now. Understanding Cambridge Analytica and the bigger AI Propaganda Machine is essential for anyone who wants to understand modern political power, build a movement, or keep from being manipulated. The Weaponized AI Propaganda Machine it represents has become the new prerequisite for political success in a world of polarization, isolation, trolls, and dark posts. "
2011. "These days at the I.B.M. Almaden Research Center in San Jose, Calif., there is not a lot of talk of reverse-engineering the brain. Wide-ranging ambitions that narrow over time, Dr. Modha explained, are part of research and discovery, even if his earlier rhetoric was inflated or misunderstood.
“Deciding what not to do is just as important as deciding what to do,” Dr. Modha said. “We’re not trying to replicate the brain. That’s impossible. We don’t know how the brain works, really.” "
“chip-first as an organizing principle gave us a coherent plan.”
"In designing chips that bear some structural resemblance to the brain, so-called neuromorphic chips, neuroscience was a guiding principle as well. Brains are low-power, nimble computing mechanisms — real-world proof that it is possible."
