Data augmentation and handling distribution shift Questions
Master augmentation techniques (random crops, flips, rotations, color jittering, mixup, CutMix). Understand why augmentation helps. Discuss domain adaptation and techniques for handling domain shift in production systems.

Contrast adversarial augmentation (e.g., FGSM/PGD-based perturbations) with random augmentations. Explain when adversarial augmentations are appropriate, how they affect robustness and calibration, and how to balance adversarial examples with natural augmentations during training in production systems.

You are responsible for reducing failure cases of an autonomous perception model by generating synthetic training examples in simulation. Describe a practical pipeline including domain randomization, targeted augmentations for corner cases, how to label automatically, and how to validate that simulated examples improve real-world performance. Mention sim2real evaluation metrics and stopping criteria.

Design a set of experiments to quantify the generalization gap between a model trained with an augmentation policy and its performance on a target domain. Specify dataset splits, cross-validation scheme, confidence intervals, hypothesis tests for significance, and how to attribute gains to augmentation vs model capacity or training time.

Describe the mixup and CutMix augmentation techniques for supervised image classification. Explain concretely how each constructs new training examples (inputs and labels), why they can improve generalization and calibration, and in which tasks or data regimes (small datasets, localization-sensitive tasks, multi-label) you might prefer one to the other. Mention label interpolation implications.

Explain covariate shift, label shift, and concept shift. For each, give a practical production example, describe why a naive augmentation strategy may or may not help, and list appropriate mitigation techniques (data augmentation, importance weighting, retraining, label correction).
