Review for NeurIPS paper: Multi-Fidelity Bayesian Optimization via Deep Neural Networks

R3 seems overly negative in a not very well justified manner. R4's review is very short and mainly indicates that the difference to the multi-fidelity modeling proposed by Cutajar et al (2019) should be made clear. I believe the authors successfully address R4's comments in the rebuttal. I recommend the authors to perform an ablation study recommended by R3 in their final version. As recommended, the experiments should be further improved based on the reviews.
