production systems (MSPS), in which model selection is achieved by sequentially deploying a list of candidate models

We thank the reviewers for the in-depth reviews. We will first answer the comments shared by multiple reviewers and then answer the individual comments. We will add additional details about sparse GP, VI and binary observation in suppl. A/B tests for a few weeks and then select the best model, which is the common scenario in industry. Model selection for a time sensitive system is an interesting and open research question for future work.
