What makes ImageNet good for transfer learning?

Why ImageNet Helps Computers Learn — and What Really Matters

People often wonder why models trained on ImageNet seems to work so well for other jobs.
Researchers tried many setups: fewer images, fewer categories, or more detailed labels, and then tested how those changes mattered on new tasks.
They trained models on slices of ImageNet, then used those skills on new jobs and saw that big changes rarely mattered much.
It turns out seeing varied pictures makes strong, general features, and tiny tweaks often don't improve much.
For a fixed amount of data, should you split it into many small classes or make few categories with lots of examples? Both can work, and neither were always best.
Finer labels help sometimes but they are not required to get useful transfer.
What really counts is variety in the images, not perfect choices in labeling.
So focus on diversity and simple, clear labels; small dataset tweaks usually won't change the final result, which lets you try new ideas faster.
