Deep learning models are often unaware of the inherent constraints of the task they are applied to. However, many downstream tasks require logical consistency. For ontology classification tasks, such constraints include subsumption and disjointness relations between classes. In order to increase the consistency of deep learning models, we propose a semantic loss that combines label-based loss with terms penalising subsumption- or disjointness-violations. Our evaluation on the ChEBI ontology shows that the semantic loss is able to decrease the number of consistency violations by several orders of magnitude without decreasing the classification performance. In addition, we use the semantic loss for unsupervised learning. We show that this can further improve consistency on data from a distribution outside the scope of the supervised training.

While Google shuttered Stadia for good this week, other cloud gaming services are expanding their offerings. NVIDIA is upgrading its GeForce Now service with a bunch of features, thanks to the addition of new SuperPODs equipped with RTX 4080 GPUs. This seems to be the first truly high-end cloud gaming experience. The renamed Ultimate plan now includes support for refresh rates of up to 240Hz at full HD or 4K at 120 fps and an expanded set of usable widescreen resolutions (3,840x1,600, 3,440x1,440 and 2,560x1,080). NVIDIA is also adding better support for HDR on both Macs and PCs, along with the ability to use full ray tracing with DLSS3 in supported games.

However, working ontologists are often surprised by how challenging and slow it can be to develop ontologies. Here, with a particular emphasis on the sorts of ontologies that are content-heavy and intended to be shared across a community of users (reference ontologies), we propose that a significant and heretofore under-emphasised contributor of challenges during ontology development is the need to create, or bring about, consensus in the face of disagreement. For this reason reference ontology development cannot be automated, at least within the limitations of existing AI approaches. Further, for the same reason ontologists are required to have specific social-negotiating skills which are currently lacking in most technical curricula.

When Marc Randolph and Reed Hastings launched the world's first online DVD-rental service in California in 1997, it was far from the behemoth that Netflix is today. Customers had fewer than 1,000 titles to choose from, and they had to pay separately for every DVD they rented. The founders nearly sold the company to Amazon for around US$15 million, and when they tried to sell it to Blockbuster forUS$50 million a few years later, Blockbuster's CEO was reported to have said to Netflix, "The dotcom hysteria is completely overblown." Fast forward two decades, and the company now has more than 200 million subscribers around the world and more than US$20 billion in annual revenue. The simple answer is'reinvention' – a requirement that can present itself to any business, but which not all business leaders have the courage or forethought to embrace.

Netflix is planning to add video games to its massive library of films and TV shows within the next 12 months, a new report claims. Games will be available on Netflix at no extra cost to the standard subscription price, according to Bloomberg, although the move may make it easier for Netflix'to justify price increases in coming years'. Netflix has also confirmed to MailOnline that it has just hired Mike Verdu, a former executive of Electronic Arts (EA), the successful video games firm, who will lead the expansion into games. At EA, Verdu previously worked on mobile games including titles in the Sims, Plants vs. Zombies and Star Wars franchises. He has also worked for Facebook and Kabam, one of the biggest creators of smartphone and tablet games.

No one wants to be reminded of a failed relationship by having the ex's portrait hanging around. After Amedeo Modigliani and his lover, Beatrice Hastings, broke up, the Italian artist is thought to have obliterated her memory by painting another woman's likeness over his portrait of her. So he might not be too happy to learn that science has now brought back that "lost" portrait, using artificial intelligence, an X-ray and 3D-printing to re-create the painting, with full colour and textured brushstrokes. Portrait of a Girl, a 1917 masterpiece, is owned by the Tate, which was taken aback in 2018 to discover an earlier portrait beneath the picture. X-rays revealed the ghostly outlines of a full-length figure, prompting the then curator, Nancy Ireson, to suggest that it was a portrait of Hastings, and that Modigliani "might have painted her out" after their intense two-year relationship ended in 1916.

Netflix might be planning to expand into the $150 billion video game industry, according to a media report. The popular streaming company is'excited to do more with interactive entertainment' beyond its popular offerings'from series to documentaries, film, local language originals and reality TV', a spokesperson told DailyMail.com. 'Members also enjoy engaging more directly with stories they love - through interactive shows like Bandersnatch and You v. Wild, or games based on Stranger Things, La Casa de Papel and To All the Boys. So we're excited to do more with interactive entertainment.' The Information, which first broke the news, reports that the Los Gatos, California-based company has approached veteran executives in the industry to lead its efforts.

Thanks to Covid-19, the mantra for 2020 has got to be "quarantine and chill." Good thing Netflix is here to "entertain people all over the world," as the company's cofounder Reed Hastings explained at this year's WIRED25. Sating the global entertainment palate, though, requires an undying spirit of invention as well as narratives that span both the US and abroad. Netflix's secret, according to Hasting's new book No Rules Rules, is that it values its workers over its work process. It's this employee-centric attitude that allows a startup to maintain a culture of innovation as it grows from, say, a 30-person rent-by-mail DVD provider into the world's largest streaming service, with a film production arm that rivals Hollywood's Big Six.

Synthetic biology is a rapidly accelerating market, with an estimated conservative global valuation of around US$14 billion.1 To polymath hacker and explorer JJ Hastings, the ability to produce fast, efficient and customisable materials enabled by machine learning and computer-aided design will change the world with an array of entirely new, advanced materials. The extraordinary is now possible: producing spider silk without spiders, egg proteins without chickens and fragrances without flowers. These materials can now be produced by renewable feedstock, reducing the need for large scale agricultural bases or energy-intensive manufacturing. The predicted impact of biomanufacturing drew US$1.7 billion in 2017 investment alone.2 Synthetic biology companies are partnering with fashion designers, heavily backed by VC dollars, as well as forming'organism foundries'.

Netflix CEO Reed Hastings has claimed that the streaming giant's biggest rivals aren't Amazon, YouTube or even traditional broadcasters. According to Mr Hastings, our need for sleep is actually its main barrier. "You know, think about it, when you watch a show from Netflix and you get addicted to it, you stay up late at night," he said. Mr Hastings stopped short of announcing a new technology capable of helping us recharge without snoozing, though he did go on to make some surprising comments about downloads. The company bowed to pressure by launching the much-requested offline viewing feature last year, but Mr Hastings doesn't think much of it.
