Abrégé

It is provided a method (and corresponding apparatuses, computer programs, and medium) for determining whether an item being processed is defective or non-defective, the method including a step of determining (S10), by a local neural network (11) and on the basis of sensing measurements performed on an item while the item is being processed, a local classification result indicating whether the item is defective or non-defective. At step S20, it is determined a confidence index indicating a level of confidence that the local classification result is correct. Then, at step S30 and in response to the confidence index being below a given threshold, it is determined, by a central neural network (21) and on the basis of the sensing measurements, a central classification result indicating whether the item is defective or non-defective, wherein the local neural network (11) has less computational resources than the central neural network (21).
