Reviews: LIIR: Learning Individual Intrinsic Reward in Multi-Agent Reinforcement Learning

The paper extends the idea of learning intrinsic rewards to the centralized learning - decentralized execution, cooperative multi-agent setting. This setting has become popular in past years, as a setting that has high potential for real world applications and being amenable to progress towards tractable solutions. The approach presented by this work is easy to conceptually simple and well motivated. The authors empirically show that it outperforms existing state of the art approaches on challenging StarCraft benchmark tasks. Reviewers raised several concerns about the paper, including clarity (experiment details, precise description of the approach and distinction from existing approaches), and the need for further analysis.
