GPU highly recommended but not required. + +**Q: Can I use CPU only?** +A: Yes, set `--device cpu` or `config.device = 'cpu'`. Training will be slower. + +**Q: How long does training take?** +A: Depends on dataset and model. CIFAR-10: 10min on RTX 3060ti + +**Q: Can I resume interrupted training?** +A: Yes, load the checkpoint and continue training. + +**Q: How do I use my own dataset?** +A: Create a custom Dataset class and use with DataLoader. + +### Technical Questions + +**Q: What's the difference between AdamW and Adam?** +A: AdamW applies weight decay correctly, usually performs better. + +**Q: When should I use mixed precision?** +A: Almost always. It's 2-3x faster with minimal accuracy impact. + +**Q: How do I prevent overfitting?** +A: Use regularization (weight decay), dropout, data augmentation, early stopping. + +**Q: What learning rate should I use?** +A: Start with 0.001, use learning rate finder to optimize. + +**Q: How many epochs do I need?** +A: Depends on dataset.
