## Quick Start

### Load Primary Benchmark Results

```python
from datasets import load_dataset

# Load main benchmark results (27,600 configurations)
ds = load_dataset("AI-EcoNet/HUGO-Bench-Paper-Reproducibility", "primary_benchmarking")
print(f"Configurations: {len(ds['train'])}")
```

### Load Pre-computed Embeddings

```python
# Load DINOv3 embeddings (120,000 images)
embeddings = load_dataset(
    "AI-EcoNet/HUGO-Bench-Paper-Reproducibility", 
    "embeddings_dinov3_vith16plus"
)
print(f"Embeddings shape: {len(embeddings['train'])} x {len(embeddings['train'][0]['embedding'])}")
```

### Load Specific Analysis Results

```python
# Model comparison results
model_comp = load_dataset("AI-EcoNet/HUGO-Bench-Paper-Reproducibility", "model_comparison")

# Scaling test results
scaling = load_dataset("AI-EcoNet/HUGO-Bench-Paper-Reproducibility", "scaling_tests")

# Intra-species variation analysis
intra = load_dataset("AI-EcoNet/HUGO-Bench-Paper-Reproducibility", "intra_species_variation")
```

### Load Cluster Image Mappings

The intra-species analysis includes a mapping file showing which images belong to which clusters:

```python
from huggingface_hub import hf_hub_download
import json

# Download mapping file
mapping_file = hf_hub_download(
    "AI-EcoNet/HUGO-Bench-Paper-Reproducibility",
    "intra_species_variation/cluster_image_mappings.json",
    repo_type="dataset"
)

with open(mapping_file) as f:
    mappings = json.load(f)

# Structure: {species: {run: {cluster: [image_names]}}}
print(f"Species analyzed: {list(mappings.keys())}")
```

### Load Full Dataset Embeddings

For the extreme uneven distribution experiments, we provide full dataset embeddings:

```python
from huggingface_hub import hf_hub_download
import pickle

# Download Aves embeddings (74,396 images)
pkl_file = hf_hub_download(
    "AI-EcoNet/HUGO-Bench-Paper-Reproducibility",
    "extreme_uneven_embeddings/aves_full_dinov3_embeddings.pkl",
    repo_type="dataset"
)

with open(pkl_file, 'rb') as f:
    data = pickle.load(f)

print(f"Embeddings: {data['embeddings'].shape}")  # (74396, 1280)
print(f"Labels: {len(data['labels'])}")
print(f"Paths: {len(data['paths'])}")
```

## Experimental Setup

- GMM (Gaussian Mixture Models)
- With and without dimensionality reduction (UMAP, t-SNE, PCA)

### Evaluation Metrics

- **Supervised**: Adjusted Rand Index (ARI), Normalized Mutual Information (NMI), Accuracy, F1
- **Unsupervised**: Silhouette Score, Calinski-Harabasz Index, Davies-Bouldin Index
