Viewing enriched Twitter post
I recently gave some talks on PointWorld. In this latest version, I discussed: Why world models? Why 3D? Why it matters amidst scaling data in robotics? Why it’s a missing side of the coin for “The Bitter Lesson”? (It’s more than just a better backbone for training policies) https://t.co/oGhLvuyB6B
