　　A work of art created by artificial intelligence (AI) has been sold by a major art seller for the first time. The print sold for an unexpectedly（意外地） large amount of $432,500. Officials had predicted it would sell for between $7,000 and $10,000. The artwork was made by a machine learning algorithm（算法）. The AI system was created by members of an art collective called Obvious in Paris, France. Three creators from the art group Obvious cooperated on the process that made the print. First, they put a collection of 15,000 portraits（肖像） into a machine learning system. The portraits were painted by artists from the time period between the 14th and 20th centuries. Then a tool called the "Generator" made a new image based on the information entered into the system. After that, another tool, called a "Discriminator," attempted（试图） to find differences between the human-made image and one created by the Generator. Obvious has created a series of AI-produced art works. The team has experimented with other kinds of historical paintings. These included subjects from nature to paintings of the whole human body. Artwork created by machine learning methods leaves open questions about who or what should get credit for creating the pieces.
