generator will fail, which model evaluation metric should be the PRIMARY focus?
B imo, because avoiding false alarms about failures (specificity) matters to prevent unnecessary downtime.
D. I get the concerns about precision and specificity, but in this case, missing a real failure could be way more costly or dangerous than a false alarm. So catching as many true failures as possible (recall) should be the priority. You can always tune the system later to reduce false positives if needed, but missing failures outright is riskier.
D, catching all failures is vital even if some false alarms happen.
A/D? I get recall is about catching all failures, but precision helps avoid too many false alarms that waste time and money. Depending on consequences, precision might be just as important as recall here.
It’s A because if we focus only on recall, we might get too many false alarms. Precision helps ensure that when the model says failure, it’s actually likely, which saves unnecessary checks and costs.
B imo, specificity matters if false positives trigger costly unnecessary checks. We don’t want to waste resources on too many false alarms while still catching real failures.
D imo, because missing a failure could cause serious damage or downtime. Better to catch most failures even if some false alarms happen. Precision isn’t as important here since safety matters more than false positives.
D. Recall should be the focus here since catching all potential failures is crucial, even if it means more false alarms. Missing a failure could be costly.
