TL;DR / TL;DW
1. Style transfer improves model robustness, but not necessarily through real painting
styles.
2. Real paintings and stylized images capture complementary invariances.
a. Real paintings improve robustness to corruptions and novel viewpoints.
b. Stylization greatly improves robustness to corruptions but harms novel viewpoint generalization.
3. Real paintings improve robustness cost-effectively.
4. Other art forms, such as sketches, cartoons, and untextured renderings are unable
to improve model robustness to the same extent as paintings.
