Reviews: PredRNN: Recurrent Neural Networks for Predictive Learning using Spatiotemporal LSTMs

Here, the authors focus on the maximum likelihood output, but it would be helpful for comparison with prior work to also report the likelihood. Additionally, the computational complexity is mentioned as an advantage of this model, but no detailed analysis or comparison is performed so its hard to know how this compares computational complexity with prior work. Minor notational suggestion: It might be easier for the reader to follow if you use M instead of C for the cell state in equation 3 so that the connection with equation 4 is clearer.
