I took envelope to mean the operating conditions under which the control system is stable. For many control systems this isn't really a confidence interval except insofar as the parameters of the control system are imperfectly known. For as long as I can remember, AI has been a synonym for "hard CS problem" or even just "hard math problem." It has more use as a marketing term than as a technical term with precise meaning.

"I took envelope to mean the operating conditions under which the control system is stable." Yes, that's exactly what I meant. I kind of borrowed the term from aviation where this is used to describe conditions under which the behavior of the aircraft is known and predictable. Doesn't mean it is not possible to fly outside the envelope, you just don't get any guarantees.

Ah gotcha, totally agree. > It has more use as a marketing term than as a technical term with precise meaning. yea exactly; not a problem for me that this is the case (buzzwords are just a fact of life), but really what should be happening underneath any "AI" solution is finding and implementing the right solution to the problem. If the right solution is classical control theory or linear models, but the business leaders insist on deep learning because to them that's what AI means, that's where there's a problem.
