Reviews: Ultrametric Fitting by Gradient Descent

Originality: For the aforementioned contributions, I believe this work provides a creative, unique approach to this problem. Quality: I believe this paper to be technically sound, a complete work that presents interesting approaches for hierarchical clustering. Clarity: The paper is written well and clearly explains the approach. But there were a some details that I thought could have been made clearer in both the presentation and in the experiments. Unless I've missed something, I think that it would be good to more clearly state the process (and its complexity) of going from the ultrametric fit to data to a dendrogram.
