The one our group made used this exact dataset (the museum website)! We called it VANGOGHORNO haha. We basically pulled the images from the collection and mixed them with non-Van Gogh paintings. It was surprisingly a very learnable dataset, the top two teams got around 97% accuracy and many teams got to 90%. We resized the images and included paintings from vaguely similar styles like impressionism so we were surprised people did that well. I think the top team used some kind of transfer learning to identify entities in the paintings and learned from that.
