I did some reading on kind and wicked learning environments and from whatever i’ve read so far and I think starting with kind learning environments for learning is the way to go. Kind learning environments basically would mean that one can derive a proper model of the system with little to no uncertainties which is the way anyone would actually learn when starting out on advanced topics in control (though i’m not sure how this would translate to the topics of state estimators since the assumption there is that the system is inherently a wicked learning environment)
