The Nature of Physical Representations and Simulations
Any simulator must be an approximation of the real world, yet our Intuitive Physics Engine must be fast in order to provide predictions in real-time, accurate enough to make those predictions useful, and provide a distribution of predictions to avoid false certainty. I study the ways the mind approximates physical processes and object representations to balance the demand for both rapid and robust simulation, as these principles can form the basis for building AI that must judge and act within the world in real-time.
