Hallucinating Humans for Learning Object Affordances
We bear in mind that the object being worked on is going to be ridden in, sat upon, looked at, talked into, activated, operated, or in some other way used by people individually or en masse. --Dreyfuss (1955).
In fact, humans are the primary reason for our environments to even exist. In this work, we show that modeling human-object relationships (i.e., object affordances) gives us a more compact way of modeling the contextual relationships (as compared to modeling object-object the relationships).
One key aspect of our work is that the humans may not be even seen by our algorithm! Given a large dataset containing only objects, our method considers human poses as a latent variable, and uses infinite topic models to learn the relationships. We apply this to the robotic task of arranging a cluttered house.
