CIFAR-100: What is the difference between vehicles 1 and vehicles 2?
The difference between vehicles 1 and vehicles 2 is that vehicles 1 are more common and vehicles 2 are less common.

CIFAR-100 dataset super/coarse labels are not very rigorous. The CIFAR-100 official documentation points out flaws in their taxonomy:


  fruit and vegetables: apples, mushrooms, oranges, pears, sweet peppers
  large carnivores: bear, leopard, lion, tiger, wolf
  …
  Yes, I know mushrooms aren't really fruit or vegetables and bears aren't really carnivores.
