Reviews: Distributed Low-rank Matrix Factorization With Exact Consensus

I would appreciate if you could incorporate the reposes from the rebuttal into the paper (in case of acceptance). Especially, -better highlighting of the contributions (moving some of the cited auxiliary results to the appendix might also be worth considering) -discussion of stochastic updates -for the promised discussion on alterative approaches: please check again if all primal-dual methods really require a'star-topology', and not just a connected graph; and include references to the literature; similar with the comment on gossip averaging: the literature discusses already many variants (respective'orders' of averaging/update steps); so please check again there as well. However, I would encourage to highlight contributions w.r.t. to previous works more clearly (e.g. Quality: The theorems all look sound; however, only asymptotic results are provided. Further, comparisons to alternative baselines (instead of DSG) would strengthen the paper. Originality & Significance: As outlined above, the significance could potentially be estimated more favorably if discussion/comparisons to strong baselines could be added.
