WebEpisodic dynamics randomization, without a rigorous theoretical justification, is the most common approach. Randomizing the domain parameters at every time step instead would drastically increase the variance, and pose a challenge to the implementations since this typically implies recreating the simulation at every step. Webrepresenting inverse dynamics of the deterministic source-domain environment is learned by the simulation data. The proposed approach offers a systematic way to transfer the policies trained in simulation into the real world without decreasing sample efﬁciency of the RL agent in contrast to domain randomization or min-max robust RL methods. dance in the parksWebfeatures of a simulation, randomized dynamics have also been used to develop controllers that are robust to uncertainty in the dynamics of the system. Mordatch et al. [21] used a trajectory optimizer to plan across an ensemble of dynamics models, to produce robust trajectories that are then executed on a real robot. Their method allowed a ... bird that cries like a baby
