Hello,
In my opinion, the "Anomaly" defined in anomaly detection should be unknown, so we shouldn't validate the algorithm on real anomaly dataset. However, we know that it's necessary to find a validation procedure to tune the hyper-parameters. Recently, I find some studies related to this:
(1) We can generate pseudo anomaly dataset to tune the model. http://medicalood.dkfz.de/web/
(2) As the number of iterations increases the model should converge to the optimum, so we may not need to use the validation set to find the best epoch. https://github.com/zhiyuanyou/UniAD
I think the study area of anomaly detection is still developing and recent studies are aiming to solve this problem.
