Natural Adversarial Examples and Out-of-Distribution Detection in Neural Networks
A foundational safety study by Dr. Dan Hendrycks introducing the ImageNet-A and ImageNet-O benchmarks, exposing fundamental vulnerabilities where vision models fail catastrophically on naturally occurring adversarial examples.
Vision classification benchmark; physical world adversarial perturbations present additional environmental dynamics.
Context: Evaluated ResNet, DenseNet, and early vision-transformer architectures under natural distribution shifts.

The industry-standard academic benchmark measuring world knowledge and problem-solving across 57 subjects ranging from elementary mathematics to professional law and medicine, authored by Dr. Dan Hendrycks.
Multiple-choice evaluation format does not directly measure multi-step agent reasoning, tool usage, or long-form generation coherence.
Context: Multiple-choice evaluation suite across 57 distinct disciplines.
