There are approximately 35,000 paintings on display at the Louvre. Most tourists feel overwhelmed by the prospect of viewing them. Indeed, if one were to devote 30 seconds to each painting (not counting the time it takes to walk between them), it would take more than twelve twenty-four hour days to visit them all.
Yet if one were to design an algorithm capable of identifying all 19th century British oil paintings, a visit to the museum would feel quite different. Indeed it would be much more efficient, as one could effectively skip those works irrelevant to one’s research. Providing the algorithm was correctly designed, one could apply it to London’s Tate Britain: the trick is in knowing which works speak to you—in my case, J. M. W. Turner’s Decline of the Carthaginian Empire.
