CSIRO Pasture Biomass Prediction (4th Place Solution)

 

This model card covers the main and auxiliary models used in the Kaggle CSIRO Pasture Biomass Prediction competition (4th place). The solution uses a ViT-Huge DINOv3 backbone with multi-modal fusion and an auxiliary pretraining stage.

Model Description

Main model (Stage 1)

• —Backbone: vit_huge_plus_patch16_dinov3.lvd1689m (DINOv3)
• —Input: RGB pasture image + tabular features (Pre_GSHH_NDVI, Height_Ave_cm)
• —Output: Biomass regression targets
• —Loss: Weighted Smooth L1 with weights [0.1, 0.1, 0.1, 0.2, 0.5]

Aux model (Stage 2)

• —Input: RGB pasture image only
• —Output: Predicts tabular features (NDVI, Height)
• —Purpose: Feature enrichment for the main model

Model Weights

• —Main model: https://huggingface.co/jatinmehra/CSIRO-DinoV3-HugePlus-LB76
• —Aux model: https://huggingface.co/jatinmehra/CSIRO-AUX_MODEL

Intended Use

• —Research and benchmarking for pasture biomass regression from aerial/ground images.
• —Demonstration of multi-modal fusion and auxiliary prediction benefits.

Out-of-Scope Use

• —Medical or safety-critical applications.
• —Real-time decision systems without domain validation.

Training Data

• —Kaggle CSIRO Pasture Biomass Prediction dataset.
• —Images were manually cropped to remove cardboard background.

Preprocessing

• —Manual cropping to remove cardboard borders.
• —Tabular features and regression targets normalized via StandardScaler.
• —Image size: 800×800.

Training Configuration

Stage 1 (Main Model)

• —Batch size: 10
• —Optimizer: AdamW
• —LR: 5e-5
• —Scheduler: CosineAnnealingWarmRestarts (T0=10, Tmult=2, eta_min=1e-6)
• —5-fold CV (Seed 42)

Stage 2 (Aux Model)

• —Batch size: 8
• —Optimizer: AdamW
• —LR: 5e-5
• —Scheduler: ReduceLROnPlateau (factor=0.5, patience=4)
• —5-fold CV (Seed 44)

Results

Limitations

• —Trained on competition data with specific capture setup; generalization to other pasture imagery may vary.
• —Large ViT-Huge backbone is compute-intensive.

Ethical Considerations

• —Dataset-specific biases may affect generalization.
• —Manual preprocessing may not be reproducible without the same data access.
