Some papers mention just ImageNet and some papers mention ImageNet 1k database? What is the difference between these 2? Are they same or is the latter one subset of the former one?

I'm working on Generative Adversarial Nets. I wanted to train it on ImageNet Database. How to download ImageNet 1k? I went to ImageNet site and created & verified my account. Then there were several links. Which one to select?

The ImageNet dataset consists of more than 14M images, divided into approximately 22k different labels/classes. However the ImageNet challenge is conducted on just 1k high-level categories (probably because 22k is just too much).

ImageNet Stats

When people mention results on the ImageNet, they almost always mean the 1k labels (if some paper uses the original 22k labels, they would surly mention it). So basically ImageNet=ImageNet-1k.

Regarding downloading the dataset. Since you are downloading ImageNet for your personal usage (GAN training) and not to participate in one of the challenges, it doesn't really matter, so just download the latest dataset labeled "Download links to ILSVRC2017 image data".
