Review for NeurIPS paper: Knowledge Augmented Deep Neural Networks for Joint Facial Expression and Action Unit Recognition

Additional Feedback: The work is a good incremental step towards understanding the relationship of AU and FER, and their influence in detecting one over the other. Figure 1: I am assuming that the dotted lines represent back-propagation steps for each module. Please clarify this in the manuscript/Figure. Sec 3.1: The explanation on using the generic knowledge as probabilities is not unique ([b]), and the usage of limited 8 AUs (there are a lot more) is not justified. While generating Table 1, it is important to note that these numbers are taken from studies which explored more AUs than mentioned in the table.
