This work presents a simple idea that works. The proposal can benefit from an improved presentation of the material and a more comprehensive related work section. In particular, prior work such as Multiaccuracy: Black-Box Post-Processing for Fairness in Classification should be cited. Besides, we strongly encourage the authors to incorporate in the final version of the paper the results presented in the rebuttal. Also, we suggest the authors present the results in a standard way that makes comparison with other work easier.
