Google is training a new artificial intelligence product on its search engine's most difficult queries.
Google has just gone public with the details of a new artificial intelligence called RankBrain, which the search giant is using to handle difficult queries. The system is being used on what one Google research scientist calls a "very large fraction" of the search queries handled by Google. RankBrain helps Google decipher the approximately 15% of phrases that the search engine has not encountered before, Bloomberg reports.
