Following the launch of Amazon's cashless, cashier-free Amazon Go convenience store in Seattle, a startup called AiFi is emerging from stealth today to announce the availability of its own checkout-free solution for retailers. But unlike Amazon Go, AiFi claims its A.I., sensor and camera network-based system can scale from a small mom-and-pop all the way up to a big retailer with tens of thousands of square feet and a hundred thousand products. Based in Santa Clara, AiFi was founded in January 2016 by Steve Gu and Ying Zheng, a married couple whose previous experience includes time spent at both Google and Apple. Gu, a PhD in computer science from Duke, worked on 3D Touch and Force Touch technologies while at Apple. He later went to Google X where he developed technologies for Google Glass. Zheng, also a PhD in computer science from Duke, first worked at Google Research, then later went to Apple, where she was a senior research scientist.

One of the most important jobs of any national leader is to quit. National liberation heroes, from George Washington to Nelson Mandela, who stepped down without being forced to, ought to be venerated for that as much as for any good they accomplished while in office. Generally, rulers do not give up power unless they have to. In Africa, peaceful transfers of power are rare enough that a billionaire has set up a generous annual prize to reward leaders who step down voluntarily; many years it goes unclaimed. Around the world, cases like Bashar al-Assad, willing to watch his country crumble rather than give up power over it, or Robert Mugabe, forced out by his own military after 47 years, are more common.

First, the futurist Amy Webb told the audience of journalists, librarians and foundation managers that they could easily be duped by the ever-growing purveyors of artificial intelligence. Images of their faces could be affixed to others' bodies, their voices to impostors. Media people have acknowledged to pollsters that they are so focused on the present that they don't pay close attention to what might be in store for them in five, 10 or 20 years. Later in her talk Wednesday before the Knight Media Forum in Miami, Webb told people of color that they weren't thought about when the creators of self-driving cars, GPS navigators, robotics and other such technologies were being developed. "My question is, what does all this mean for communities of color?" (video) asked Sara Lomax-Reese, president and CEO of black talk-formatted WURD radio in Philadelphia. She was one of about 500 at the sold-out conference sponsored by the John S. and James L. Knight Foundation. "It's not good," replied Webb. "Any person of color who's ever felt invisible, you're totally invisible to the networks. Right?" said the author of the 2016 book "The Signals Are Talking: Why Today's Fringe Is Tomorrow's Mainstream: Forecast and Take Action on Tomorrow's Trends, Today."

The Samsung Galaxy S9 and S9 have a new camera with Super Slow-mo video, low light capability and AR Emoji for a more personalized way to express yourself. Samsung Galaxy S9 comes in three colors in the U.S. This one is lilac purple. BARCELONA--Put it this way, Samsung left the radical changes to Apple. The Galaxy S9 and S9 smartphones that Samsung introduced at a crowded press gathering here in Barcelona don't look a whole lot different than last year's S8 and S8 handsets.

Since, MICE assumes missing at random values. Let's seed missing values in our data set using prodNA function. You can access this function by installing missForest package.

A NASA spacecraft on its way to investigate a nearby asteroid has caught a remarkable glimpse at the orbital dance of Earth and the moon from far away. In a new image shared today by the space agency, Earth and its only natural satellite are the two brightest specks in a black sky. The Osiris-Rex spacecraft snapped the incredible photo from 39.5 million miles away, as it flew by at 19,000 miles per hour (8.5 kilometers per second). A NASA spacecraft on its way to investigate a nearby asteroid has caught a remarkable glimpse at the orbital dance of Earth and the moon from far away. Osiris is on its way to the near-Earth asteroid'Bennu,' in a mission to collect a 2.1-ounce sample and return it to Earth for study.

BEIJING – China has started building the world's largest test site for unmanned ships -- a technology with both civilian and military applications -- off a port in the disputed South China Sea, state media has reported. The test area is being constructed off the southern port city of Zhuhai bordering Macau, China's official Xinhua News Agency said Tuesday. China asserts sovereignty over almost all the South China Sea despite competing partial claims from the Philippines, Vietnam, Malaysia and Brunei, and has reclaimed several islands which it controls to bolster its claims. Unmanned or "autonomous" ship technology, still in its infancy, would allow both civilian and military craft to be remotely controlled. It could revolutionize the shipping industry by creating more cargo space on unmanned ships, which would also save huge sums in labor costs.

Drone delivery is expected to take off big time in the next few years. Chinese online retailer JD.com has already launched drone delivery in four provinces in China, while DHL and Zipline are delivering medicines with drones in rural and hard-to-reach areas. Amazon, Google, and UPS are all working on getting drone delivery service off the ground. There are a lot of issues to think about when it comes to package delivery using drones--safety, privacy, and logistics being some of the main concerns. In a new study, researchers tackle two other important aspects: energy use and greenhouse gas emissions.

Imagine a situation where a group of adversaries is preparing an attack on the United States or U.S. interests. An intelligence analyst has observed some signals, but the situation is rapidly changing. The analyst faces the decision to alert a principal decision maker that an attack is imminent, or to wait until more is known about the situation. This warning decision is based on the analyst's observation and evaluation of signals, independent or correlated, and on her updating of the prior probabilities of possible scenarios and their outcomes. The warning decision also depends on the analyst's assessment of the crisis' dynamics and perception of the preferences of the principal decision maker, as well as the lead time needed for an appropriate response. This article presents a model to support this analyst's dynamic warning decision. As with most problems involving warning, the key is to manage the tradeoffs between false positives and false negatives given the probabilities and the consequences of intelligence failures of both types. The model is illustrated by revisiting the case of the attack on Pearl Harbor in December 1941. It shows that the radio silence of the Japanese fleet carried considerable information (Sir Arthur Conan Doyle's "dog in the night" problem), which was misinterpreted at the time. Even though the probabilities of different attacks were relatively low, their consequences were such that the Bayesian dynamic reasoning described here may have provided valuable information to key decision makers.

Artificial intelligence is one of the most celebrated and hyped concepts today. From science fiction to the nightly news, AI has been making record headlines, whether it will become the most dangerous technology around or the one most likely to save humanity. Cryptocurrencies and blockchain, once the territory of dark net denizens and righteous Redditors, are topics of conversation in even the most venerable and stodgy of publications. What happens when you combine the two? Decentralized blockchain technology may hold the key to tapping AI's potential in a democratized way, one that opens participation in the AI economy of the future to more than just a tiny handful of the largest technology behemoths.
