We thank the reviewers for their critical assessment of our work, and for the overall positive reception. With stronger correlation there is a larger norm and more regularization. We will clarify this in the paper. There are 6 controller parameters and 5 connection qualities (from excellent to poor). The embedding sizes are set to be 1 in the simulation studies.

It's so hard to speak to a real person on the phone these days. Almost any time you need to call your bank, doctor or any other service, you'll probably be greeted by an automated service seemingly designed to prevent you from speaking to someone who actually works for the company. And that could soon get worse thanks to the rise of chatbots. Chatbots are artificial intelligence programs, often deployed in apps or messaging services. They are designed to answer people's questions in a conversational style rather than just pointing them towards information like a search engine.
