Q&A: Phase 41.3 — AdversarialTrainer

Ask questions about the AdversarialTrainer component — covering PGD adversarial training, TRADES, AWP, curriculum adversarial training, and robustness-accuracy trade-offs.

Topics

• PGD-AT vs TRADES: when to use which
• TRADES β parameter tuning
• AWP warmup strategy and γ selection
• Curriculum vs constant-epsilon training
• Robust overfitting and mitigation strategies
• Computational cost of adversarial training
• Multi-step vs single-step training (Free-AT, YOPO)
• Integration with RobustnessVerifier (41.2) for certified adversarial training
