Review for NeurIPS paper: Reconstructing Perceptive Images from Brain Activity by Shape-Semantic GAN
Weaknesses: (a) The paper falls short in providing a clear theoretical backing for using the U-Net structure in the generator. The explanation in Section 2.4 seems to suggest that the U-Net structure was selected due to the benefits of its bottleneck passing low-level features, but later states that it is only passing high-level features. Clarification of this section is needed. As the brain encodes the LVC signals into the HVC signals, the information from HVC signals should also be contained in the LVC signals. Why then, do we need the high level representation for the decoding problem?
