Doubt on Data Collection

[paolopertino]

Good morning. I have a doubt on the data contained in the COYO-700M dataset you provide. Specifically, I cannot fully understand this part of your description: "Removed all duplicate images based on the image pHash value from external public datasets. ImageNet-1K/21K, Flickr-30K, MS-COCO, CC-3M, CC-12M". Does this mean that in the COYO dataset there are not images coming from those widely known/used datasets?
Thanks a lot in advance.
