Review for NeurIPS paper: Convolutional Tensor-Train LSTM for Spatio-Temporal Learning

Weaknesses: The two major weaknesses are a lack of comparison to previous work by Yang et. Although, it does not rely on the same structure as this work (smooth evolution over time in video data vs tensor train), it does rely on somewhat of a similar structure (i.e. Looking at these two side by side, I appreciate their difference, however I think they're still too similar to not require a comparison. One could conceivably imagine that the same underlying structure is exploited by both approaches, which diminishes the novelty of the work. It remains to be seen whether this application of tensor train is orthogonal to the application of tensor train by Yang et.
