Review for NeurIPS paper: Compact task representations as a normative model for higher-order brain activity

This is a nice contribution in that it combines several different approaches (efficient coding, neuroscience/neural modeling, MDPs) in a conceptually novel way (R1, R4, R5), with R4 commenting that it's likely to be of great impact to the wider community. On the other hand, R3 saw limited conceptual novelty and believes that some prior work on policy compression has been understated. In general, I'm inclined to agree with other reviewers that it's fairly well-positioned with regard to prior work (R1). R4 praised the clarity of the writing, and other reviewers didn't have any issues with the presentation. R5 expressed concern that the results are mainly qualitative, and not particularly novel, despite the novelty of the approach itself.
