Abstract
Methods and systems for observation prediction in autonomous vehicles are described. A set of observations is received, including a current observation and one or more previous observations. Each observation includes a respective view of the environment and a vehicle state at each time step. A current action is received. A current-action embedded view is produced, the current-action embedded view representing an estimated change in vehicle state caused by the current action in a current view. A predicted view is generated from the current-action embedded view and the set of observations. The predicted view is re-centered. A predicted observation is fed back, including the re-centered predicted view and estimated change in vehicle state, to be included in the set of observations as input for multi-step training of the action-based prediction subsystem.
