Measuring Robustness to Natural Distribution Shifts in Image Classification

Taori, Rohan, Dave, Achal, Shankar, Vaishaal et al.

Understand

We study how robust current ImageNet models are to distribution shifts arising from natural variations in datasets.

  • Most research on robustness focuses on synthetic image perturbations (noise, simulated weather artifacts, adversarial examples, etc.), which leaves open how robustness on synthetic distribution shift relates to distribution shift arising in real data.
  • Informed by an evaluation of 204 ImageNet models in 213 different test conditions, we find that there is often little to no transfer of robustness from current synthetic to natural distribution shift.
  • Moreover, most current techniques provide no robustness to the natural distribution shifts in our testbed.
