what is a 'clean run'?

[HeYDwane3]

When looking at the validation README, I found the following paragraph, can anyone tell me what does 'clean run' mean?

Thanks!

The test set results include rank and top-1/top-5 differences from clean validation. For the "Real Labels", ImageNetV2, and Sketch test sets, the differences were calculated against the full 1000 class ImageNet-1k validation set. For both the Adversarial and Rendition sets, the differences were calculated against 'clean' runs on the ImageNet-1k validation set with the same 200 classes used in each test set respectively.

'Clean' means on ImageNet-1k instead of the adversarial or rendition datasets. Those datasets only use a subset of imagenet-1k labels so I re-run with just those labels and use that as the comparison point for the alternate test sets.
