This paper has weaknesses to address:
* The major weakness of this paper is the extremely limited experiments section. There are many experiments, yet almost no explanation of how they're run or interpretation of the results. Most of the results are written like an advertisement, mostly just stating the method outperforms others. This leaves the reader unclear why the performance gains happen. Ultimately it's not clear when/why the findings would generalize. The result is that some claims appear to be quite overstated. For example, L423-L424 states *"embeddings of domains with shared high-level semantics cluster together, as depicted in Appendix E.1. For example, embeddings of mono and stereo audio group closely, as do those of banking and economics."* But this is cherry-picked---Temperature is way closer to Mono and Stereo Audio than Banking is to Economics.
* Similarly, many important experimental details are missing or relegated to the Appendix, and the Appendix also includes almost no explanations or interpretations. For example, the PCA experiments in Figures 3, 7, and 8 aren't explained.
* It's unclear how many variables actually overlap between training/testing, which seems to be a key element to make the model outperform others. Yet this isn't analyzed. Showing that others fail by ignoring other variables should be a key element of the experiments.
