  • #Facebook is using AI to make detailed maps of where people live | The Verge

    The project is part of Facebook’s Connectivity Lab, the technical arm of its #Internet.org initiative that deals with #drones, #satellites, and lasers for delivering #internet to rural areas and developing countries. With better maps, the company is able to determine whether Wi-Fi hotspots or cellular technologies are better for bringing people online — and helping them sign up for Facebook naturally.

    FACEBOOK ANALYZED 20 COUNTRIES COVERING 21.6 MILLION SQUARE KILOMETERS

    To generate the maps, Connectivity Lab worked with Facebook’s data science division, infrastructure unit, and #machine_learning and #artificial_intelligence groups.

    OK.

  • Google utilise l’intelligence artificielle pour les 15% de requêtes qu’il n’a encore jamais reçues

    Début 2014 Google avait racheté #DeepMind, spécialisé dans l’intelligence artificielle, pour 365M€. Il s’agissait là d’un talent acquisition. C’est de là que provient le responsable Technologie de Google, Demis Hassabis, qui annonçait près d’un an plus tard la coopération avec l’université d’Oxford afin d’approfondir leur algorithmes de Machine Learning.

    Le fruit de leurs recherches porte le nom de #RankBrain.
    Quand Google ne reconnait pas un mot ou une phrase, RankBrain tente de deviner/prédire quel mot ou phrase aurait une signification similaire. De cette manière le moteur de recherche serait plus apte à fournir une réponse à une toute nouvelle requête et à des questions ambiguës.

    For the past few months, a “very large fraction” of the millions of queries a second that people type into the company’s search engine have been interpreted by an artificial intelligence system, nicknamed RankBrain, said Greg Corrado, a senior research scientist with the company, outlining for the first time the emerging role of AI in search.

    RankBrain uses artificial intelligence to embed vast amounts of written language into mathematical entities — called vectors — that the computer can understand. If RankBrain sees a word or phrase it isn’t familiar with, the machine can make a guess as to what words or phrases might have a similar meaning and filter the result accordingly, making it more effective at handling never-before-seen search queries.

    [...]

    The addition of RankBrain to search is part of a half-decade-long push by Google into AI, as the company seeks to embed the technology into every aspect of its business. “Machine learning is a core transformative way by which we are rethinking everything we are doing,”
