What if I told a story here, how would that story start?" Thus, the summarization prompt: "My second grader asked me what this passage means: …" When a given prompt isn't working and GPT-3 keeps pivoting into other modes of completion, that may mean that one hasn't constrained it enough by imitating a correct output, and one needs to go further; writing the first few words or sentence of the target output may be necessary.
WASHINGTON – U.S. officials said Thursday it was "highly likely" that an Iranian anti-aircraft missile downed a Ukrainian jetliner late Tuesday, killing all 176 people on board. They suggested it could well have been a mistake. The crash came just a few hours after Iran launched a ballistic missile attack against Iraqi military bases housing U.S. troops amid a confrontation with Washington over the U.S. drone strike that killed an Iranian Revolutionary Guard general last week. Two U.S. officials, speaking on the condition of anonymity to discuss sensitive intelligence, said they had no certain knowledge of Iranian intent. But they said the airliner could have been mistaken for a threat.
The potential for advances in information-age technologies to undermine nuclear deterrence and influence the potential for nuclear escalation represents a critical question for international politics. One challenge is that uncertainty about the trajectory of technologies such as autonomous systems and artificial intelligence (AI) makes assessments difficult. This paper evaluates the relative impact of autonomous systems and artificial intelligence in three areas: nuclear command and control, nuclear delivery platforms and vehicles, and conventional applications of autonomous systems with consequences for nuclear stability. We argue that countries may be more likely to use risky forms of autonomy when they fear that their second-strike capabilities will be undermined. Additionally, the potential deployment of uninhabited, autonomous nuclear delivery platforms and vehicles could raise the prospect for accidents and miscalculation. Conventional military applications of autonomous systems could simultaneously influence nuclear force postures and first-strike stability in previously unanticipated ways. In particular, the need to fight at machine speed and the cognitive risk introduced by automation bias could increase the risk of unintended escalation. Finally, used properly, there should be many applications of more autonomous systems in nuclear operations that can increase reliability, reduce the risk of accidents, and buy more time for decision-makers in a crisis.
We propose a novel neural topic model in the Wasserstein autoencoders (WAE) framework. Unlike existing variational autoencoder based models, we directly enforce Dirichlet prior on the latent document-topic vectors. We exploit the structure of the latent space and apply a suitable kernel in minimizing the Maximum Mean Discrepancy (MMD) to perform distribution matching. We discover that MMD performs much better than the Generative Adversarial Network (GAN) in matching high dimensional Dirichlet distribution. We further discover that incorporating randomness in the encoder output during training leads to significantly more coherent topics. To measure the diversity of the produced topics, we propose a simple topic uniqueness metric. Together with the widely used coherence measure NPMI, we offer a more wholistic evaluation of topic quality. Experiments on several real datasets show that our model produces significantly better topics than existing topic models.
Tesla shares have plunged this morning after Elon Musk smoked marijuana and drank whiskey while discussing everything from drugs to the possibility we're all living in a simulation, in a rambling two-and-a-half hour podcast appearance which was live-streamed on YouTube. The 47-year-old billionaire went on the Joe Rogan Experience late on Thursday night and accepted a joint from the host - after a rambling conversation that also took in the dangers of AI and the possibility China is spying on US citizens through their phones. Hours later, the company's chief accounting officer Dave Morton resigned citing'public attention' on the company. Meanwhile, shares plummeted to nine per cent this morning, wiping $4.3 billion off the company's value. By close of trading they had slightly recovered to a 6.3 per cent drop, reducing the company's value by $3.1bn. It follows weeks of serious turbulence for both Musk and Tesla, after he falsely announced he was taking the company private in a deal with Saudi Arabia and accused a British hero diver of being a paedophile.
U.S. officials have told airlines to "be prepared" for an expanded ban on carry-on electronic devices allowed on airplanes. Homeland Security spokesman David Lapan confirmed to reporters Tuesday that the administration is considering expanding the ban on laptops, which currently applies to U.S.-bound flights from eight countries in the Middle East and North Africa. An expanded ban on devices larger than cellphones could potentially include "more than a couple" other regions, including flights from Western Europe. Lapan reminded reporters that DHS Secretary John Kelly has alluded to the ban "likely" being expanded. DHS officials, however, are still deciding where and how the new restrictions will be implemented.
The UK will ban people from flying into the country with large electronic devices by Saturday. The Department for Transport said that it will implement the ban on laptops and tablets from a range of countries this week. Any large gadgets flying from a range of affected countries will have to be put into the luggage hold, and can't be taken onto the plane. Airlines are being told to implement the rules "over the coming days and no later than 25 March", a DfT spokesperson said. Passengers "should go to the airport with the expectation that the measures are already in effect", she said.
We spoke to The Daily Beast to help make sense of ISIL's growing use of armed consumer drones in the conflict in Syria and Iraq. Meanwhile, we assisted The Verge in confirming that the jail sentence given to a Seattle man for crashing his drone during a parade was in fact unprecedented in the history of U.S. domestic drone use. A suspected U.S. drone strike in Pakistan killed two individuals near the border of Afghanistan. If confirmed, it would be the first U.S. drone strike in Pakistan under the Trump administration. The U.S. launched over 20 airstrikes in Yemen, targeting al-Qaeda in the Arab Peninsula.
Dronescapes is a collection of vibrant, mystical paintings of drones by Australian artist Kathryn Brimblecombe-Fox. In a conversation with the Center for the Study of the Drone, the artist shares the meaning of her work, explains her use of traditional Australian motifs, and shares her views on the rise of autonomous technology. The Federal Aviation Administration released a new set of reports of airspace incidents involving drones, including close encounters with manned aircraft and drone use over airports. The dataset includes 1,274 reported incidents that occurred between February and September 2016, around 400 more than occurred during the same period in 2015. At the National Interest, Elsa Kania argues that China could soon overtake the U.S. in the development of autonomous drones.
In what would make an excellent sidekick for Batman, scientists have built a fascinating, unconventional flying robot that moves its wings and flies just like a bat. Covered with a thin, silicon skin, the flexible wings of this mechanical creature-- called Bat Bot-- can move like bat wings do, making use of nine different artificial joints (real bats have far more joints). Anyone who's ever seen a bat flap around at dusk knows they are incredible flyers, and Soon-Jo Chung, one of the flying robot's creators, said that he gets "mesmerized" by bats' impressive flight skills, with their quick turns and perching. "Bat flight is the holy grail of aerial robotics," Chung, an associate professor at CalTech and a research scientist at NASA's Jet Propulsion Laboratory, said during a conference call with reporters on Tuesday. The flying robotic creation is very different from a typical artificial flying device, like a quadrotor drone that uses spinning propellers.
