  "account": "On 23 June 2021 the Rijksmuseum in Amsterdam displayed Rembrandt's The Night Watch with reconstructions of the strips cut from all four sides in 1715. The canvas was trimmed to fit a wall in the Town Hall. Rijksmuseum senior scientist Robert Erdmann trained artificial neural networks on the original and on a seventeenth-century copy attributed to Gerrit Lundens. They generated the missing sections in his style. Printed reconstructions were mounted around the original for the following months. Director Taco Dibbits said: “Thanks to this reconstruction, we can now see that the composition as it was painted by Rembrandt was even more dynamic.” Hyperallergic reported the project independently on 24 June 2021.",

The canvas was trimmed to fit a wall in the Town Hall. Rijksmuseum senior scientist Robert Erdmann trained artificial neural networks on the original and on a seventeenth-century copy attributed to Gerrit Lundens. They generated the missing sections in his style. Printed reconstructions were mounted around the original for the following months. Director Taco Dibbits said: “Thanks to this reconstruction, we can now see that the composition as it was painted by Rembrandt was even more dynamic.” Hyperallergic reported the project independently on 24 June 2021.",
