Google uses a machine-learning artificial intelligence system called “Rank Brain” to help sort its search results. Wondering how it works and fits into Google's overall ranking system? Here's what we know about Rank Brain. The information covered below comes from three original sources and has been updated over time, with notes on updates. Here are those sources: The Phone Number List first is the Bloomberg story that broke the Rank Brain news Second, additional information that Google has now provided directly to Search Engine Land Third, our own knowledge and best guesses where Google doesn't provide answers. We will specify where these sources are used, where deemed Phone Number List necessary, apart from general information. What is Rank Brain? Rank Brain is Google's name for a machine learning artificial intelligence system used to Phone Number List help process its search results, as reported by Bloomberg and also confirmed by Google. What is Machine Learning? Machine learning is where a computer learns to do something, rather than being taught by humans or following detailed programming. What is Artificial Intelligence? True artificial intelligence, or AI for short, is where a computer can be as intelligent as a human being, at least in the sense of gaining knowledge both by learning and building on what he knows and making new Phone Number List connections. True AI only exists in science fiction novels, of course. In practice, AI is used to refer to computer systems designed to learn and make connections. How is AI different from machine learning? In terms of Rank Brain, it seems to us that they are quite synonymous. You may hear the two being used interchangeably, or you may hear machine learning used to describe the type of artificial intelligence approach used. So Phone Number List Rank Brain is the new way Google ranks search results? Rank Brain is part of Google's overall search "algorithm", a computer program used to sort through the billions of pages it knows and find those deemed most relevant to particular queries. What is the name of Google's search algorithm? google-hummingbird1-ss-1920 It's called Hummingbird, as we've reported in the past. For years, the Phone Number List global algorithm had no formal name. But in mid-2013, Google overhauled this algorithm and gave it a name, Hummingbird.
