Computer says there is a 80.58% probability painting is a real Renoir

Staring enigmatically at an unseen object to her right, the black-haired woman bears a striking resemblance to the person depicted in Pierre-Auguste Renoir's painting Gabrielle, which Sotheby's recently valued at between £100,000-150,000. However, art connoisseurs disagree over whether the work, which is owned by a private Swiss collector, is the real deal. Now, artificial intelligence has waded in to help settle the dispute, and the computer has deemed that it probably is a genuine Renoir. AI is increasingly being used to help adjudicate on whether valuable artworks are real or fake. Earlier this month, Art Recognition, the Swiss company that developed the technology, announced it had concluded that Switzerland's only Titian – a work titled Evening Landscape with Couple, held by Kunsthaus Zürich – was probably not painted by the 16th-century Venetian artist.
