The D&A method takes a (partial or full) video of any robot performing any task plus a text description and produces an off-the-shelf reward model with no training. Demonstrated on the SGS locomotion task; notably, D&A only grants extra reward when the goal is visible in the image, showing its reward signal aligns with the visual goal.
