⚡ RAM Optimizations

Training Configuration:

• Epochs: 2 (high-quality fine-tuning)
• Batch Size: 32 (RAM safe)
• Target Samples: 16K (reduced for RAM)
• Pin Memory: Enabled
• Num Workers: 2 (parallel loading)
• Device: GPU (CUDA) or CPU
• Expected RAM: ~5-6GB during training
• Training Time: ~1.5 hours

RAM Safety Strategy:

• Reduced samples: 16K vs 30K (47% less data)
• Smaller batches: 32 vs 64 (50% less per batch)
• Same dataset diversity: All 50 datasets still used
• Per-dataset targets unchanged
• Should stay well under 12GB RAM

📦 Dataset Strategy

Real Images (30 Datasets) - UNCHANGED:

• Core datasets: beans, cats_vs_dogs, tiny-imagenet, flowers, oxford-pets
• Classification: cifar10, mnist, fashion_mnist, caltech101, food101
• Specialized: stanford_dogs, gtsrb, eurosat, aircraft, sun397
• Medical/Scientific: patch_camelyon, NIH chest x-rays
• Target: ~8K real images with minimal synthetic (<1.5K if needed)

Fake Images (20 Datasets) - UNCHANGED:

• GAN datasets: AFHQ, pokemon, wikiart, metfaces, celeba
• Style transfer: winter2summer, horse2zebra, watercolor2photo
• Diffusion models: pokemon-gpt4-captions, few-shot-universe
• Target: ~8K fake images with minimal synthetic (<1.5K if needed)

🎯 Key Features

1. 2 Epochs: High-quality fine-tuning from V11 base
