The Pentagon's No. 2 civilian official said Wednesday that the Defense Department is concerned that adversary nations could empower advanced weapons systems to act on their own, noting that while the United States will not give them the authority to kill autonomously, other countries might. Deputy Defense Secretary Robert O. Work said the Pentagon hasn't "fully figured out" the issue of autonomous machines, but continues to examine it. The U.S. military has built a force that relies heavily on the decision-making skills of its troops, but "authoritarian regimes" may find weapons that can act independently more attractive because doing so would consolidate the ability to take action among a handful of leaders, he said. "We will not delegate lethal authority to a machine to make a decision," Work said. "The only time we will… delegate a machine authority is in things that go faster than human reaction time, like cyber or electronic warfare."

E: I kicked around the idea of Cosmify for about 4 months after I left Yahoo. I lack some of the data analysis background to pull what I wanted to build off, so I asked around and met with a long list of scientists in the Bay Area, Japan, China, and Russia. A friend and famous Python guru (the Python language is one of pillars of exploratory data analysis; R is the other) introduced me to Ana - she has tremendous programming chops and is a well known scientist specialized in reproducible research. She liked the idea of creating an unstructured data analysis system that anybody could use. Turned out too that we have common friends working at Trinity College in Dublin, where she earned her PhD and where I lectured a few times as a guest speaker about advanced large systems programming.

When monkeys teach monkeys, it's a monkey that you get. When humans teach monkeys, you get a more advanced monkey, who may not know what he really is. Now when humans teach humans, you get humans. But what happens, when machines teach humans? This question is not that far in the future anymore, in fact it's happening right now.

A team of Nevada scientists have been using a drone to control the weather. Engineers and meteorologists say they have created the first autonomous cloud seeding platform that could increase rainfall by 15 per cent. Cloud seeding involves spraying fine particles of silver iodide into a cloud system in an effort to boost the amount of rain that falls. A team of Nevada scientists have been using drones to control the weather. Microscopic particles of silver iodide are shot into existing clouds using land based generators or aircraft.

The Times has assembled a panel of distinguished and diverse writers who will regularly contribute to the Books section. The 10 authors who make up the Los Angeles Times Cultural Critics At Large have published works of fiction, nonfiction and poetry. They have won dozens of prizes. A majority have deep connections to Southern California, even though they hail from four different nations. They will help expand the literary conversation, challenging ideas and broadening readers' understanding of literature and culture within the contemporary moment.

Amazon thrilled comic book fans recently when it announced it was moving forward with its revival of "The Tick," a new live-action series based on the comics by Ben Edlund that have already spawned an animated series, a short-lived live-action series (both on Fox) and a video game. Rumors have swirled for several years, and the streaming content provider announced March 10 that it had ordered a pilot for a new take on the comics, featuring an all new cast. Stepping into the considerable footsteps of Patrick Warburton, who served as the voice of the animated Tick and embodied the live-action version of the character, is British actor Peter Serafinowicz ("Guardians of the Galaxy," "Shaun of the Dead.") Say what you will about "Batman v Superman: Dawn of Justice" (and people have said plenty), at 2 hours and a 33 minutes -- packing in three of the comic-book realm's biggest icons, a psychotic supervillain, a giant alien monster and more plot threads than you can shake a kryptonite-tipped spear...

In news that may leave fans questioning the direction of the latest reboot of "The Tick," creator Ben Edlund says the new series would have a slightly different tone than expected. Speaking to Entertainment Weekly, Edlund remarked, "We've got this show about superheroes [where] we get to have fun with the idea of superheroes," before going on to say that the series would be, "darker and more grounded."

Microsoft doubled down on its message of Windows apps that can work on your PC, smartphone or Xbox One during Build 2016, its annual developers conference in San Francisco. Central to this idea was the big Windows 10 Anniversary update, which further opens up the operating system to developers. Chatbots and Cortana were also featured prominently as a potential future for Microsoft in a world that has left the desktop behind. "I am an optimist," Microsoft CEO Satya Nadella said Wednesday during the Build 2016 keynote. "We, as a company, are optimistic about what technology can do for us. I believe technology can, in fact, drive economic growth all over the world. I believe technology can empower us in our daily lives. I believe technology can be used to preserve our enduring values."

For two of the datasets we are using a small sample for testing. The OpenStreetMap data is limited to edits in Azerbaijan from 2012 and earlier, and the Git data is just from the Django GitHub repository. The datasets we have selected span a wide range of densities, user and item counts, and types of ratings. Additionally, they provide a wide variety of information about items and users allowing us to explore different methods of extracting content vectors from the datasets.

Last week, Microsoft released an AI chatbot on Twitter with disastrous results. Though the TayTweets robot began life with innocent-enough tweets, it eventually started to spew hateful rhetoric about feminism, immigrants, and even claimed that the Holocaust didn't happen. It was a PR nightmare for Microsoft, and the tech giant eventually pulled the plug on their creation after 15 hours. Out of all the hateful things the chatbot said, there was one which was very amusing considering which company created it. The A.I. was asked whether Sony's PlayStation 4 or Microsoft's own Xbox One was the better system.
