Reviews: Curvilinear Distance Metric Learning

This paper had somewhat mixed reviews, with two positive reviews and one negative review. After the rebuttal, I also took a look at the paper and initiated a discussion with the reviewers. The main concerns of the negative reviewer were in the comparison to existing non-linear metric learning approaches; I also had a similar concern when reading the paper. I think the rebuttal responded well to this (also, it's unrealistic that one could compare with many of the existing non-linear approaches, given how many exist); please include the new results in the final version. My other concern was that the writing is often not super clear---for example, terms like "measurer lines" are not ever precisely defined, and may be unfamiliar to readers who work on metric learning.
