Two important tasks at the intersection of knowledge graphs and natural language processing are graph-to-text (G2T) and text-to-graph (T2G) conversion. Due to the difficulty and high cost of data collection, the supervised data available in the two fields are usually on the magnitude of tens of thousands, for example, 18K in the WebNLG dataset, which is far fewer than the millions of data for other tasks such as machine translation. Consequently, deep learning models in these two fields suffer largely from scarce training data. This work presents the first attempt to unsupervised learning of T2G and G2T via cycle training. We present CycleGT, an unsupervised training framework that can bootstrap from fully non-parallel graph and text datasets, iteratively back translate between the two forms, and use a novel pretraining strategy. Experiments on the benchmark WebNLG dataset show that, impressively, our unsupervised model trained on the same amount of data can achieve performance on par with the supervised models. This validates our framework as an effective approach to overcome the data scarcity problem in the fields of G2T and T2G.

Volkswagen's ID.3 EV finally has an official release date. Consumers in most European countries will be able to put a deposit on the EV starting on June 17th. Those who do will have two delivery options. They'll be able to get the EV either as soon as possible or later in the year. The earliest deliveries will take place in September, with the latter ones scheduled for Q4 2020.

The news: IBM has said the company will stop developing or selling facial recognition software due to concerns the technology is used to promote racism. In a letter to Congress, IBM's CEO Arvind Krishna said the tech giant opposes any technology used "for mass surveillance, racial profiling, violations of basic human rights and freedoms." He called for a "national dialogue" on whether and how it is appropriate for facial recognition technology to be used by domestic law enforcement agencies. The letter also called for new federal rules to crack down on police misconduct, and more training and education for in-demand skills to improve economic opportunities for people of color. Not a new concern: Activists and experts have been pointing out for years that facial recognition systems are biased, and flagging concerns about its potential for abuse.

The government could ban loot boxes amid accusations they allow children to gamble. Officials have launched a new consultation into the technology and whether it is damaging children who play games like Fifa, which include them. Loot boxes – which are known under a variety of different names in individual games – allow people to buy a collection of items without knowing what will be inside of them. After a person has bought one, either with real money or by playing, they receive whatever is inside, which could include in-game items that can be sold for real currency. Critics argue that the technology allows children to gamble and encourages such behaviour. A number of child welfare organisations, charities and other groups have warned that the technology could lead to addiction later in life.

Simulated warfare between artificial intelligence participants has revealed that "extraordinary forms" of extreme weaponry evolve when combatants fight each other in one-to-one in duels. Researchers at the University of Auckland in New Zealand pitted AI players against each other in a war game to better understand how animals evolve weapons. They found that combatants with improved weapons had a large advantage when fighting in duels, but that this advantage deteriorated when there were more rivals to fight against. The findings suggest that arms races between animals and in other types of conflict are more likely to be accelerated when there are only two opponents. The study was based on a current evolutionary hypothesis that predicts the evolution of elaborate weaponry in duel-based systems, such as the exaggerated horns wielded by male dung beetles and stag deer when fighting over females.

Reddit has announced its replacement for Alexis Ohanian, who stepped down from the company's board of directors last week. Ohanian said he wanted his position filled by a black candidate. That person is Michael Seibel, the CEO of startup accelerator Y Combinator. Seibel was also the founder of Justin.tv, He was Y Combinator's first black partner before he became CEO, and has supported donating to causes that promote the Black Lives Matter movement.

Babylon Health has been responsible for providing users with buggy software that shared recordings made by other patients. It was discovered that its video GP consultation feature could be accessed by other patients. Babylon Health allows users to speak to health specialists via a smartphone app and can send an electronic prescription to nearby pharmacies. In the UK it has 2.3 million users. No international users were affected.

Nintendo has confirmed that hackers breached 300,000 accounts since April. Hackers had access to personal information including users' birthdays and email addresses, but did not have access to credit card information. Nintendo reported unauthorised logins on 24 April, where it was thought that approximately 160,000 accounts had been accessed by malicious actors, the company wrote in a Japanese language blog post. The company now understands that the breach was nearly twice as large, with passwords "obtained illegally by some means other than our service". It is resetting user passwords for affected account as well as disabling the option to log into a Nintendo account through a Nintendo Network ID (NNID).

Strava has made a major change to how its famous "segments" work, seeking to reward effort. Traditional segments – which give achievements for quickly completing certain stretches of road – will still exist in the app, and are unchanged. But they will appear alongside the new feature, which aims to reward people for how often they do a certain segment, not how fast. Runners and cyclists will no longer have to be the fastest person to be at the top of the leaderboard, but to do the most efforts on that particular segment. The changes come as Strava makes major alterations to its platform in an attempt to encourage users to join its paid tier, as part of a plan to make more money from subscriptions.

Mourners pay respects to George Floyd in Houston; reaction and analysis on'The Five.' IBM has quit the facial recognition technology business, citing concerns that it can be used for mass surveillance and racial profiling. The move comes amid ongoing protests following the death of George Floyd on May 25--while in police custody in Minneapolis--that have thrust racial injustice and police monitoring technology into the spotlight. The tech giant's CEO Arvind Krishna explained IBM's decision in a letter sent to U.S. lawmakers Monday. "IBM no longer offers general purpose IBM facial recognition or analysis software," he wrote. "IBM firmly opposes and will not condone uses of any technology, including facial recognition technology offered by other vendors, for mass surveillance, racial profiling, violations of basic human rights and freedoms, or any purpose which is not consistent with our values and Principles of Trust and Transparency."
