[r/ML] [D] Why I abandoned YOLO for safety critical plant/fungi identification. Closed-set classification is a silent failure mode

Summary

A developer building a device for identifying plants and fungi discovered a critical flaw in YOLO models despite achieving high initial accuracy. YOLO's closed-set architecture confidently misclassifies out-of-distribution images, posing a significant safety risk for identifying toxic species, as it lacks an 'I don't know' option. This highlights a 'silent failure mode' in AI for safety-critical applications.
