Review for NeurIPS paper: An Imitation from Observation Approach to Transfer Learning with Dynamics Mismatch

Weaknesses: -The cost function formulation is similar to previous work of [17] and [43]. The adversarial objective minimized is based on prior work of [17] and [43]. Given this, the proposed approach does not offer significant technical novelty. However, the experiments are based on sim-to-sim evaluation where there are two simulator for a task and one of them is called'real'. I do not see such characterization as acceptable.
