Artificial Intelligence (AI) approaches to problem-solving and decision-making are becoming more and more complex, leading to a decrease in the understandability of solutions. The European Union's new General Data Protection Regulation tries to tackle this problem by stipulating a "right to explanation" for decisions made by AI systems. One of the AI paradigms that may be affected by this new regulation is Answer Set Programming (ASP). Thanks to the emergence of efficient solvers, ASP has recently been used for problem-solving in a variety of domains, including medicine, cryptography, and biology. To ensure the successful application of ASP as a problem-solving paradigm in the future, explanations of ASP solutions are crucial. In this survey, we give an overview of approaches that provide an answer to the question of why an answer set is a solution to a given problem, notably off-line justifications, causal graphs, argumentative explanations and why-not provenance, and highlight their similarities and differences. Moreover, we review methods explaining why a set of literals is not an answer set or why no solution exists at all.

Despite the ubiquity of drones nowadays, it seems to be generally accepted that learning how to control them properly is just too much work. Consumer drones are increasingly being stuffed full of obstacle-avoidance systems, based on the (likely accurate) assumption that most human pilots are to some degree incompetent. It's not that humans are entirely to blame, because controlling a drone isn't the most intuitive thing in the world, and to make it easier, roboticists have been coming up with all kinds of creative solutions. There's body control, face control, and even brain control, all of which offer various combinations of convenience and capability. The more capability you want in a drone control system, usually the less convenient it is, in that it requires more processing power or infrastructure or brain probes or whatever. Developing a system that's both easy to use and self-contained is quite a challenge, but roboticists from the University of Pennsylvania, U.S. Army Research Laboratory, and New York University are up to it--with just a pair of lightweight gaze-tracking glasses and a small computing unit, a small drone will fly wherever you look.

A 24-year-old Dallas man who died after falling off a Lime electric scooter was killed by blunt force injuries to his head, county officials said Thursday, likely making him the first person to die while riding the electric mobility devices that have swept across the nation this year. The death of Jacoby Stoneking has been ruled an accident, the Dallas County Medical Examiner's Office told The Washington Post before releasing the information publicly. Police said Stoneking was riding a Lime scooter home from a restaurant where he works when the accident occurred. He was found unconscious and badly injured in the early morning hours of Sept. 1, several hundred yards from a scooter that was broken in half. He was not wearing a helmet, according to a person familiar with the matter who spoke on condition of anonymity to talk freely about the investigation. The determination by Dallas officials emerged just after California Gov. Jerry Brown (D) signed a bill Wednesday that makes it legal for adults to ride electric scooters without a helmet.

"The question here is about the data," Ms. Vestager said, adding that the investigation was in its "very early days" and that her office has "no conclusions" about whether to open a formal probe. A spokesman for Amazon didn't have any immediate comment. As the EU's antitrust chief, Ms. Vestager has emerged as one of the world's major technology regulators, helping inspire investigations into tech companies from Brazil to the U.S. Most recently, she fined Alphabet Inc.'s Google twice, for a total of €6.76 billion ($7.9 billion), for allegedly abusing the dominance of its search engine and Android operating system to favor its own services--decisions the company has either appealed or said it would appeal. Under her watch, the EU also ruled that Amazon must pay some €250 million in allegedly unpaid taxes to Luxembourg, an order that the Seattle-based company has appealed. Amazon is also drawing increasing scrutiny in its home country.

ANGELA MERKEL, Germany's chancellor, has a reputation for being dour. But if she wants to, she can be quite funny. When asked at a recent conference organised by Ada, a new quarterly publication for technophiles, whether robots should have rights, she dead-panned: "What do you mean? The interview was also striking for a different reason. Mrs Merkel showed herself preoccupied by artificial intelligence (AI) and its geopolitics. "In the US, control over personal data is privatised to a large extent.

It seems one cannot pick up a newspaper or magazine in 2018 without seeing a headline related to artificial intelligence (AI). In September 2018, The Wall Street Journal published a thought-provoking article, The Human Promise of the AI Revolution. Taking an opposite and certainly a more sensationalist approach, Newsweek had this headline in its Tech & Science section, Forget Terrorism, Climate Change and Pandemics: Artificial Intelligence is the Biggest Threat to Humanity.

The following is an interview with Daniel Wagner, ahead of the release of his new book, AI Supremacy: Winning in the Era of Machine Learning. Can you briefly explain the differences between artificial intelligence, machine learning, and deep learning? Artificial intelligence (AI) is the overarching science and engineering associated with intelligent algorithms, whether or not they learn from data. However, the definition of intelligence is subject to philosophical debate-even the terms algorithms can be interpreted in a wide context. This is one of the reasons why there is some confusion about what AI is and what is not, because people use the word loosely and have their own definition of what they believe AI is. People should understand AI to be a catch-all term for technology which tends to imply the latest advances in intelligent algorithms, but the context in how the phrase is used determines its meaning, which can vary quite widely. Machine learning (ML) is a subfield of AI that focuses on intelligent algorithms that can learn automatically (without being explicitly programmed) from data.

Nasa's Curiosity mission has ground to a halt on Mars after a glitch forced the $2.5 billion (£2 billion) rover to terminate all of its science experiments. Mission team members say the inter-planetary science lab can no longer beam data stored in Curiosity's memory banks back to Earth, effectively rendering it useless until the issue is resolved. Researchers said they are unsure what triggered the computer glitch and that it could be'some time' before engineers manage to diagnose and fix the problem. Mission team members are also preparing to fire up the backup computer inside Curiosity, in case they need the separate system to diagnose the mysterious issue plaguing the main computer. It follows one of the biggest Martian dust storms on record, which at its peak covered covered 14 million square miles (36 million sq km), knocking out Nasa's solar-powered Opportunity rover for three months.
