How Facebook scales Artificial Intelligence
Facebook's products and services are powered by machine learning. Powerful GPUs have been one of the key enablers, but it takes a lot more hardware and software to serve billions of users. Most of Facebook's two billion users have little idea how much the service leans on artificial intelligence to operate at such a vast scale. Facebook products such as the News Feed, Search and Ads use machine learning, and behind the scenes, it powers services such as facial recognition and tagging, language translation, speech recognition, content understanding and anomaly detection to spot fake accounts and objectionable content. The numbers are staggering. In all, Facebook's machine learning systems handle more than 200 trillion predictions and five billion translations per day. Facebook's algorithms automatically remove millions of fake accounts every day. In a keynote at this year's International Symposium on Computer Architecture (ISCA) , Dr. Kim Hazelwood, the...
