Dear Yanshen, Thanks for your answer, do not worry about the timing, and find my answer in-line :-).

For me that depends on the algorithmic representation. We have two types of variables: - Measurable and controllable variables, such as the load of a resource managed by the solution, which can be known and can be altered by some decision of such solution (increase/decrease the amount of resources). - Measurable but non-controllable, which are outside the control of the solution. They can be known and used to take decisions but cannot be altered (directly or indirectly) by the solution. A simple example can be found in the occurrence of some event that can affect to a system, such as the number of attendees to a baseball match. The management solution cannot control such variable but uses it to determine the amount of network resources assigned to the network of the stadium. > A simple case is the ML algorithm, such as reinforcement learning, > needs "rewards" to correct the error and improve its model during > iterations.

Those rewards are "controllable variables", and thus must be introduced to the whole loop, so the management solution uses them, and maybe other information, to determine actions that will change/improve them. > BTW, I think there should be some methods to support the "reward" > feedback.

That is a good option for a new draft, but it would be more related to other WG than to IDNET "per se". I find it very interesting so, if you plan to work on it, please count on me. I think we can circulate some initial version to the NMRG and from there we can see where it fits. > Maybe there is room for the future. > > Thanks for your reply and suggestions. > > Yansen Let's be in contact...
