Left-sorted Bongard Problems have the keyword "visualimagination" on the OEBP.
Many things might be called "creating a picture". For example, drawing a path in a maze. However, use this keyword to indicate a Bongard Problem requires the solver to create something totally new "on a separate piece of paper" (whether mentally or physically), beyond just annotating the existing picture.
An artificial intelligence for solving such Bongard Problems should need some sort of ability to invent its own pictures internally. |
