TAFC.SPACE has a post which includes a map of the world as seen by a topologist. I.e. it doesn't show sizes or locations of countries, just which countries are next to which other countries. The actual map is near the bottom of the post but it's worth scrolling for.

An article in Nature reports on scientists who trained a deep-learning system with a large number of photographs of human retinas. After training, the system was able to identify the sex of the people in the photos with >80% accuracy. This is interesting because there is no known difference between male and female retinas. Naturally the system can't tell us how it tells the difference.
