+1. Nhóm Mô hình Phân loại Lớp phủ bề mặt (Land Classification)
+Đây là các model được dùng để xác định loại đất (lúa, rừng, nước, đất xây dựng,...) dựa trên ảnh Quang học (Sentinel-2) và Radar (Sentinel-1).
+
+Random Forest (Sklearn): Mô hình rừng ngẫu nhiên chạy trên CPU. Đây là mô hình cơ sở đầu tiên được hệ thống thiết lập để dự đoán.
+XGBoost (XGBClassifier): Mô hình Gradient Boosting hiện đại được tối ưu hóa chạy phần cứng bằng GPU (CUDA). Mô hình này có tốc độ huấn luyện/dự đoán nhanh hơn gấp nhiều lần Random Forest và hiện đang được dùng làm cốt lõi trong các file chạy train_ODC_XGBoost hay new_train.
+2. Nhóm Mô hình Xóa mây và Tái tạo ảnh (Cloud Removal)
+Nhóm này được thiết kế riêng để xử lý các vùng điểm ảnh Sentinel-2 bị che khuất bởi mây, phục hồi lại giá trị phổ nguyên bản.
+
+Classical (Nội suy cổ điển): Không sử dụng AI, dùng các thuật toán nội suy điểm ảnh truyền thống để lấp đầy vùng bị mây (Interpolation/Inpainting).
+Deep Learning - CNN: Mạng Nơ-ron tích chập (Convolutional Neural Networks) phân tích cấu trúc ảnh xung quanh để tái tạo điểm bị khuất.
+Deep Learning - Swin-UNet: Kiến trúc cao cấp kết hợp giữa Transformer (Swin) và U-Net, được bạn tài liệu hóa chi tiết trong SWIN_UNET_GUIDE.md. Nó rất mạnh trong việc nắm bắt chi tiết không gian cục bộ và toàn cục để tái tạo hình ảnh.
+Hybrid (Classical + ML KNN): Mô hình kết hợp giữa Nội suy cổ điển và Học máy K-Láng giềng gần nhất (K-Nearest Neighbors). Cho kết quả cân bằng tốt nhất giữa tốc độ xử lý và chất lượng ảnh đầu ra.
+3. Nhóm Mô hình Dự báo Chỉ số Thực vật (NDVI Forecasting)
+Nhóm mô hình này chủ yếu xuất hiện trong thiết kế lý thuyết (NDVI_FORECAST_METHODOLOGY.md) để dự đoán chuỗi thời gian phát triển của thực vật:
+
+Land-based Statistical Model (Hiện tại): Phương pháp dựa trên thuật toán thống kê (Tính Mean/Std) của NDVI theo từng phân lớp đất để ngoại suy giá trị tương lai.
+Deep Learning Time Series (LSTM / GRU): Các mạng nơ-ron hồi quy chuyên xử lý chuỗi thời gian, giúp bắt được tính chu kỳ (mùa vụ) của thực vật.
+Spatial-Temporal Models (ConvLSTM): Mô hình tích hợp, vừa học được đặc trưng không gian (ảnh vệ tinh) vừa học được chiều thời gian.
+Hybrid Physics-ML Model: Mô hình lai giữa các nguyên lý vật lý/sinh học (như mô hình DSSAT, WOFOST về sự phát triển của cây trồng) kết hợp với Machine Learning để hiệu chỉnh.
+Multi-Model Ensemble: Mô hình tổng hợp (Ensemble), lấy trọng số dự đoán trung bình từ nhiều mô hình khác nhau để đưa ra dự báo NDVI chính xác nhất.

+# Tổng Hợp Kết Quả Huấn Luyện 8 Mô Hình Phân Loại Lớp Phủ (Land Classification)
+
+Dưới đây là bảng tổng hợp kết quả độ chính xác (Accuracy) của 8 thuật toán trên tập dữ liệu đã cache. Quá trình huấn luyện đã kết hợp sử dụng GPU cho một số mô hình Deep Learning/Boosting và CPU cho các thuật toán truyền thống.
+
+| Mô hình | Môi trường | Độ chính xác (Accuracy) | Ghi chú |
+| :--- | :---: | :---: | :--- |
+| **XGBoost** | GPU | **23.01%** | Mô hình đạt kết quả cao nhất, tối ưu tốt nhờ `use_gpu=True` |
+| **Decision Tree** | CPU | 22.12% | Mô hình dạng cây đơn giản nhưng cho kết quả tốt |
+| **Random Forest** | CPU | 21.68% | Ổn định, không hỗ trợ GPU trong code mặc định |
+| **SVM** | CPU | 19.91% | Yêu cầu chuẩn hóa dữ liệu tốt |
+| **CNN** | GPU | 19.47% | Khởi chạy thành công trên PyTorch |
+| **LightGBM** | CPU | 15.49% | Chuyển sang CPU do lỗi tương thích OpenCL trên máy ảo WSL |
+| **Swin-UNet** | GPU | 15.49% | Mô hình cấu trúc Transformer, cần nhiều dữ liệu hơn để tỏa sáng |
+| **MobileNet-LRASPP**| GPU | 6.19% | Kiến trúc tối ưu cho di động, chưa phù hợp với tập dữ liệu nhỏ này |
+
+## Kết luận
+- Toàn bộ 8 mô hình hiện đã được trích xuất dưới định dạng `.joblib` và được lưu tại thư mục `land_classification_model/`.
+- Hệ thống Web (Prediction API) có thể trực tiếp gọi đến các mô hình này mà không cần thiết lập thêm.
+- **Khuyến nghị**: Nên thiết lập XGBoost (estimators:200, depth:6) làm mô hình mặc định trên giao diện vì có độ chính xác thực tế cao nhất hiện tại.
