The system was fed about 30 hours of videos depicting simple actions like two balls bouncing off each other or a ball rolling down a slope.<\/p>\n<blockquote><p>\u201cLuckily for us, developmental psychologists have spent decades studying what infants know about the physical world and cataloging the different ingredients or concepts that go into physical understanding. Extending their work, we built and open-sourced a physical concepts data set. This synthetic video data set takes inspiration from the original developmental experiments to assess physical concepts in our models,\u201d<\/p><\/blockquote>\n<p>Piloto said.<\/p>\n<h2>Solidity, Continuity, And Persistence<\/h2>\n<p>PLATO was able to gain the ability to predict how objects would behave in different circumstances.<\/p>\n<blockquote><p>\u201cIn particular, it learned patterns such as continuity, in which an object follows an uninterrupted trajectory rather than magically teleporting from one place to another; solidity, which prevents two objects from penetrating each other; and persistence of the objects\u2019 shape.
