Review for NeurIPS paper: A simple normative network approximates local non-Hebbian learning in the cortex

Weaknesses: The empirical evaluation is one of the weakest aspects of the paper. The fact that this is done on only one, seemingly arbitrarily chosen, dataset diminishes the significance of the results. I would have liked to see evaluation on more standard datasets. There are some aspects of the biological mapping that may not be biologically plausible: - Only linear model are considered. In biology, pyramidal cells are known to have many non-linear effects.
