Can a single cs-NF detect defects of objects of multiple categories? #11

Thanks for excellent work and code! I notice every category needs a cs-NF in released code. Here I have a question: Can a single cs-NF detect defects of objects of multiple categories?

Yes it works, but the performance is slightly lower as for the individual classes. In the case of MVTec, the detection AUROC dropped by 0.5% on average.

Thank you the explanation！
