Internet Services Tech Industry Artificial intelligence (AI) Facebook Tags Comments Share your voice 3 Facebook CTO Mike Schroepfer says Facebook’s AI can distinguish between images of marijuana (left) and broccoli tempura (right). Screenshot by Stephen Shankland/CNET Facebook uses both human beings and artificial intelligence to combat some of its toughest problems, including hate speech, misinformation and election meddling. Now, the social network is doubling down on AI.The tech giant has come under fire for a series of lapses, including its failure to pull down a live video of terrorist attack in New Zealand that killed 50 people at two mosques. Content moderators who review posts shared by the social network’s 2.3 billion users say they’ve suffered trauma from repeatedly looking at gruesome and violent content. But AI has also helped Facebook flag spam, fake accounts, nudity and other offensive content before a user reports it to the social network. Overall, AI has had mixed results.Facebook CTO Mike Schroepfer on Wednesday acknowledged that AI hasn’t been a cure-all for the social network’s “complex problems,” but he said the company was making progress. He made the remarks in a keynote at the company’s F8 developer conference.Schroepfer showed the audience photographs of marijuana and broccoli tempura, which look surprisingly similar. Facebook employees, he said, built a new algorithm that can detect differences in similar images, allowing a computer to distinguish which was which.Read more: CBD: What it is, how it affects the body and who it might helpSchroepfer said similar techniques can be used to help machines recognize other images that might otherwise escape the social network’s detection.”If someone reports something like this,” he said, “we can then fan out and look at billions of images in a very short period of time and find things that look similar.”Facebook, which doesn’t allow the sale of recreational drugs on its platform, discovered that people tried to work around its system by using packaging or baked goods, such as Rice Krispies treats. The social network can now flag those images by putting together signals like the text in a post, comments and the identity of the user.”This is an intensely adversarial game,” Schroepfer said. “We build a new technique, we deploy it, people work hard to try to figure out ways around this.”Identifying the right images isn’t the only AI challenge the company is facing. When the company was building a smart camera for its Portal video chat device, Facebook had to make sure the technology wasn’t biased and could recognize age, gender and skin tone.Facebook is also trying to train its computers to learn with less supervision in order to tackle hate speech in elections. But as the social network uses AI to moderate more content, it also has to balance concerns that it’s being fair to all groups. Facebook, for example, has been accused of suppressing conservative speech, but the company has denied those allegations. And people might disagree about what’s considered hate speech or misinformation. Facebook data scientist Isabel Kloumann said in an interview that when the company is determining what is hate speech the identity of the person could be an important factor along with who they’re targeting. At the same time, Facebook has to balance safety concerns with whether they’re treating groups of people equally.”We don’t have a silver bullet for this,” she said. “But the fact that we’re having this conversation is the most important thing.”Originally published May 1, 1:46 p.m. PTUpdate, 5:19 p.m.: Adds comments from Facebook data scientist and more background.
Fourth-placed Liverpool were stung by a 1-0 defeat at Premier League basement side Swansea City who withstood a second-half onslaught to secure the points after taking the lead through defender Alfie Mawson at the Liberty Stadium on Monday.Swansea went ahead five minutes before the break when an attempt to clear by Liverpool’s 75 million pounds ($104.88 million) defender Virgil Van Dijk landed at the feet of Mawson who swept the ball home for his sixth league goal this season.Van Dijk, playing in his first league game since signing from Southampton, had earlier flashed over a header from a first-half corner, while Mohamed Salah blazed the Dutch defender’s lofted pass over the bar on the half-hour mark.Liverpool upped the tempo in the second half, dominating possession and attacking from all angles, and Roberto Firmino saw his late header come back off the post, but Swansea managed to hold on for only their fifth league win of the season.Liverpool had not lost in 18 games, having just ended the unbeaten league record of runaway leaders Manchester City, but they fluffed their lines in the face of some stout defending.The loss leaves the Reds on 47 points, three behind Chelsea and six off Manchester United, with Tottenham Hotspur two points outside the top four after a draw at Southampton on Sunday.Manchester City lead the way with 65 points from 24 games.SWANSEA FORMULA”I told my players: Liverpool is a strong team. Like a Formula 1 car,” Swansea boss Carlos Carvalhal told Sky Sports after a win that took his side level on 20 points with second-bottom West Bromwich Albion and three off the safety zone.advertisement”If you put that F1 car in the 4pm London traffic, the F1 car will not drive very fast. That’s exactly what we had to do. Let them play in a way they don’t like.”The plan seemed to work as the visitors struggled to find a way through the Swansea defence in the first half. Van Dijk looked composed but a lack of movement in front of him limited his options as he brought the ball out of defence.Mawson’s goal lit a fire under the Liverpool attack and they surged forward after the break, notching 17 of their total 21 attempts on goal in the second period.
zoom Port of Rotterdam was proclaimed ‘Port of the Year’ during the annual ‘Containerisation International Awards’ in London. The expert jury praised the port for its substantial investment programme in Europe’s leading logistics hub and industrial complex. The jury also compliments the port with its attention to sustainability with their modal shift objectives and groundbreaking initiatives like InlandLinks and NextLogic that contribute to it.Emile Hoogsteden, director of Containers, Breakbulk and Logistics at the Port of Rotterdam Authority: “Winning this award is a tremendous achievement and recognition of our efforts. As the port of Rotterdam, we are constantly working on new investments and innovations. We don’t do this alone, but in partnership with as many market parties as possible. This is the only way we can continue to improve our port and pursue our ambition to be the most efficient, safe and sustainable port in the world. A good example of this is obviously the development of Maasvlakte 2. This is a project with which we are investing in the future and not only responding to the increasing volume size of containerships, but also taking steps towards optimising the logistical supply chain. At the same time, we enable our clients to achieve economies of scale. That’s the aim of joint ventures like P3, which will also boost our total throughput in the short and long term. Rotterdam leads today, by planning for tomorrow.”Increasing volumeAccording to the World Economic Forum, Rotterdam had the best port infrastructure in the world in both 2012 and 2013. During the period 2008-2015, businesses will make joint investments totalling over €11 billion in the port of Rotterdam, €1.2 billion of which is in container terminals. With this Rotterdam is responding to the increasing number of large 13,000 – 18,000 TEU vessels, already reflected in P3’s decision to send their largest ships to Rotterdam. Volume in the port is expected to further increase once the container terminals on Maasvlakte 2 become operational. Ben Vree, European CEO at APM Terminals: “Although the frequency of calls made by container vessels to Rotterdam may decline in the coming year, the volume will continue to increase. Combined with the state-of-the-art infrastructure and the improved efficiency in ship and cargo handling, Rotterdam’s future looks very bright. So I think the port of Rotterdam deserved to win.”About the Containerisation International AwardThe Containerisation International Awards is an initiative of publisher Containerisation International. Every year, prizes are awarded to businesses and private individuals which made a unique contribution to container liner shipping and the logistics sector in the previous year by being innovative, proactive and/or pioneering. The nominees for the ‘Port of the Year’ award were DP World’s Jebel Ali Port, the Maritime and Port Authority of Singapore (MPA), the Port of Long Beach and the Port of Rotterdam.Port of Rotterdam, October 25, 2013
Facebook rachète Instagram, l’appli de partage de photoLundi, Mark Zuckerberg, PDG de Facebook, a annoncé que le réseau social avait racheté Instagram, l’application de partage de photos destiné aux appareils mobiles. Un rachat qui lui a coûté un milliard de dollars en actions et en numéraire. Alors qu’elle vient tout juste de débarquer sur les dispositifs Android, c’est un nouveau tournant pour l’application de partage de photos Instagram. Lundi, Facebook a en effet annoncé par la voix de son PDG Mark Zuckerberg qu’il venait tout juste de racheter l’application créée il y a presque deux ans. “Je suis heureux de partager avec vous la nouvelle que nous avons accepté de racheter Instagram et que leur talentueuse équipe va rejoindre Facebook”, a indiqué le directeur sur sa page Facebook.

Maintenant nous allons pouvoir travailler encore plus étroitement avec l’équipe d’Instagram qui offre les meilleures expériences pour partager de belles images prises sur des appareils mobiles”, a t-il également ajouté cité par l’AFP. De leur côté, les créateurs d’Instagram se sont également réjouis du rachat : “Quand Mike (Krieger) et moi avons créé Instagram il y a presque deux ans, nous avons voulu changer et améliorer la manière dont le monde communique et partage. Nous avons pris beaucoup de plaisir à voir Instagram se transformer en communauté vibrante à travers le monde”, a commenté Kevin Systrom, directeur général d’Instagram, dans un communiqué.Quant au devenir de l’application, le directeur a voulu rassurer les utilisateurs, elle gardera son indépendance. “Instagram ne va pas disparaître. Nous allons travailler avec Facebook pour bâtir un réseau. Nous allons continuer à ajouter des caractéristiques au produit pour trouver de nouvelles manières de créer une meilleure expérience photo”, a t-il précisé. Un projet confirmé par Mark Zuckerberg : “Nous pensons que ces systèmes différents vont se compléter” mais pour cela “nous devons avoir en tête de garder et solidifier les forces et les caractéristiques d’Instagram plutôt que d’essayer de tout intégrer à Facebook”. Alors que le réseau social prépare son entrée en bourse, le PDG a ajouté que “c’est la première fois que Facebook fait l’acquisition d’une entreprise avec tant d’utilisateurs”. Toutefois, “nous ne prévoyons pas d’en faire beaucoup d’autres de la sorte, s’il y en a d’autres”.Le 10 avril 2012 à 09:06 • Maxime Lambert
