In neural abstractive summarization, the conventional sequence-to-sequence (seq2seq) model often suffers from repetition and semantic irrelevance. To tackle the problem, we propose a global encoding framework, which controls the information flow from the encoder to the decoder based on the global information of the source context. It consists of a convolutional gated unit to perform global encoding to improve the representations of the source-side information. Evaluations on the LCSTS and the English Gigaword both demonstrate that our model outperforms the baseline models, and the analysis shows that our model is capable of reducing repetition.

We detail our ongoing work in Flint, Michigan to detect pipes made of lead and other hazardous metals. After elevated levels of lead were detected in residents' drinking water, followed by an increase in blood lead levels in area children, the state and federal governments directed over $125 million to replace water service lines, the pipes connecting each home to the water system. In the absence of accurate records, and with the high cost of determining buried pipe materials, we put forth a number of predictive and procedural tools to aid in the search and removal of lead infrastructure. Alongside these statistical and machine learning approaches, we describe our interactions with government officials in recommending homes for both inspection and replacement, with a focus on the statistical model that adapts to incoming information. Finally, in light of discussions about increased spending on infrastructure development by the federal government, we explore how our approach generalizes beyond Flint to other municipalities nationwide.

All the G7 nations have agreed at their summit in Canada on the importance of a "rules-based trading system", despite tensions with the US. The joint statement signed by US President Donald Trump and his counterparts comes amid a row over high US tariffs imposed this month on steel and aluminium imports. The EU and Canada have taken steps to retaliate. Mr Trump says tariffs are needed to reverse America's trade deficit. Soon after the joint statement was announced, the US president tweeted defiantly about not allowing "other countries to impose massive tariffs and trade barriers on its on farmers, workers and companies".

A centre for artificial intelligence and public policy is looking to address the unique issues New Zealand will face, and is currently facing, in the era of AI. The centre has been launched in Otago and will explore policy options for managing the introduction of technologies, to maximise their benefits and minimise potential harms. Co-director of the centre, Professor James Maclaurin, said New Zealand's size sets it apart from other countries and it is important to have people acting in an advisory role. "Europe has just passed its general data protection regulations but it is a very big player so if they pass laws Facebook and Google really have to listen to them. "New Zealand is a different environment."

Artificial intelligence evokes hope and anxiety. Will we master it, or will it control us? Kwame A. A Opoku and Tendai Joe think a lot about artificial intelligence -- where it's come from and what lies ahead -- from different perspectives. Opoku is a futurist, global business speaker and founder of the think tank, Idea Factory Africa. Joe is involved in software and mobile application development, and digital publishing.

EA started off its EA Play show at E3 answering a question on everyone's lips: Will Battlefield V follow the shooter vogue and have its own battle royale mode? While the game's leads introducing the feature offered no details, the franchise's Twitter account tweeted that it will have team play and vehicles. Time will tell if the game puts its own spin on the mode or is just trying to cash in on the zeitgeist, but at least it won't have loot boxes. Royale is coming to #Battlefield V, reimagined with the core pillars of destruction, team play, and vehicles. It will be unlike anything you've played before, and we'll have more to talk about later this year.

Battle Royale is coming to Battlefield 5. During today's EA Play livestream, DICE confirmed a battle royale mode coming to Battlefield 5. That's about all the information we got about the new mode, though we learned that it will be different (somehow) from any battle royale game out now, with all of the things that make Battlefield distinct, such as destructible environments and vehicles. Many people seem to think that we already have a saturated battle royale market for some reason, despite having just two actual contenders in that space. You could hear some audible groaning in the crowd when the battle royale mode was announced. The thinking seems to be that battle royale is a trend and that trend-chasing is foolish.

In a bid to ease tensions over trade, in particular U.S. tariffs on steel and aluminum that infuriated other G7 members, officials were working on language about the international rules-based system that would lead the way to reforming the World Trade Organization, the official said.

Google has promised not to use AI for weapons, following protests over its partnership with the US military. A decision to provide machine-learning tools to analyse drone footage caused some employees to resign. Google told employees last week it would not renew its contract with the US Department of Defense when it expires next year. It has now said it will not use AI for technology that causes injury to people. The new guidelines for AI use were outlined in a blog post from chief executive Sundar Pichai. When Google revealed that it had signed a contract to share its AI technology with the Pentagon, a number of employees resigned and thousands of others signed a protest petition.

While we've already covered a lot of AI stories this week a few slipped under the radar so, as is traditional, here's the roundup of some news you may have missed. Google turns peacenik: Under fire for helping the US military use AI to better bomb people, Google has not only stepped away from that particular Pentagon contract but also this week released a set of seven principles for the development of AI. CEO Sundar Pichai made a point of noting that they are "not theoretical concepts; they are concrete standards that will actively govern our research and product development and will impact our business decisions." And they are pretty good: be socially beneficial (the AI equivalent of'Do no evil'?); They also sparked Twitter's CEO Jack Dorsey to ponder out loud whether they were something the tech industry as a whole could get around.
