🎉 Implementation Complete - Full PyTorch Workflow

✅ Hoàn thành Toàn Bộ

Tôi đã tạo workflow hoàn chỉnh để:

• ✅ Kéo dữ liệu từ S3 trên server
• ✅ Lưu thành file NetCDF (nhỏ gọn)
• ✅ Train model CNN với PyTorch trên máy local
• ✅ Predict trên toàn bộ dataset
• ✅ Xuất kết quả (NetCDF, GeoTIFF, PNG, JSON)

📝 Files Đã Tạo

🔴 Notebooks (3 files)

1. 01.prepare_data_on_server.ipynb

• Vị trí: Server
• Mục đích: Tải S3 → Xử lý → Lưu NetCDF
• Output: data_for_training/ (150-300 MB)
• Thời gian: 1-3 giờ

2. 02.train_CNN_PyTorch_local.ipynb

• Vị trí: Local Machine
• Mục đích: Train CNN model
• Output: model_cnn_pytorch_full.pt + training_history.png
• Thời gian: 30 min - 2 giờ

3. 03.predict_CNN_PyTorch_local.ipynb

• Vị trí: Local Machine
• Mục đích: Predict classification map
• Output: land_use_prediction.{nc, tif, png, json}
• Thời gian: 10-30 phút
