Supplementary material: Enhanced Meta Reinforcement Learning using Demonstrations in Sparse Reward Environments

We will use the well known Performance Difference Lemma [16] in our analysis. We can obtain a performance difference lemma for the meta-policies as follows. Here, we get (a)is from Assumption 3.1 from which we have P In this section, we describe all the simulation and real-world environments in detail. B.1 Simulation Environments Point 2DNavigation: Point 2DNavigation [9] is a 2 dimensional goal reaching environment with S R2, A R2, and the following dynamics, xt+1 = xt +dxt, yt+1 = xt +dyt, such that dx2t +dy2t 0.12 Where xt and yt are the x and y location of the agent, dxt and dyt are the actions taken which correspond to the displacement in the x and y direction respectively, all taken at time step t. The goals are located on a semi circle of radius 2, and the episode terminates when the agent reaches the goal or spends more than 100time steps in the environment.
