hi, think you'd find this interesting:

uses fault tree analysis to derive likely sources of failure based on subsystems and their relationships. think these methods are empirically useful when straight out of the factory line, but i think tacking on a sort of joint discovery process (grounded q&a session?) along with classification could probs be a good tool to help folks land in a ballpark

was working on something similar with audio classification + ecu logs and research agents checking against manuals for my project truck
