If you use PID to stabilize an unstable system, is that in the top-right corner of the cartoon map? I suppose there are implicit "prediction bands" also with standard PID control in the sense that the gain and phase margins have to be sufficient. The plant has to exist within a certain range. There is no need to do it, but I guess it is possible to visualize a possible range of open loop short time ahead forecasts based on the allowed plant range, from the at-present state. Bit contrived maybe.
Ben, one question regarding the work of Shalev-Shwartz. The tweet you linked is much more concise than what you describe. Do you have a reference for that handy? Thank you.
