Query: Follow the Object: Curriculum Learning for Manipulation Tasks with
  Imagined Goals   Learning robot manipulation through deep reinforcement learning in
environments with sparse rewards is a challenging task. In this paper we
address this problem by introducing a notion of imaginary object goals. For a
given manipulation task, the object of interest is first trained to reach a
desired target position on its own, without being manipulated, through
physically realistic simulations. The object policy is then leveraged to build
a predictive model of plausible object trajectories providing the robot with a
curriculum of incrementally more difficult object goals to reach during
training. The proposed algorithm, Follow the Object (FO), has been evaluated on
7 MuJoCo environments requiring increasing degree of exploration, and has
achieved higher success rates compared to alternative algorithms. In
particularly challenging learning scenarios, e.g. where the object's initial
and target positions are far apart, our approach can still learn a policy
whereas competing methods currently fail.
