DINOv2-base Fine-tuned on FGVC-Aircraft (100 Variants)

This model classifies aircraft photos into 100 fine-grained variant classes (e.g. 737-800, A320, Cessna 172). It is part of the Aviation Intelligence System — a ZHAW semester project.

Model Details

• Backbone: facebook/dinov2-base (86M params, self-supervised pre-training)
• Task: 100-class fine-grained image classification
• Training data: FGVC-Aircraft (6,700 images) + Wikimedia Commons extras (2,001 images) = 8,701 total
• Training: 20 epochs, AdamW (lr=5e-5), cosine schedule, label smoothing (0.1), RandAugment + RandomErasing
• Hardware: Google Colab T4 GPU, ~60 min

Performance

Metric	Value
Top-1 accuracy	84.5%
Top-5 accuracy	97.0%
Macro-average F1	0.84

Evaluated on the FGVC-Aircraft test split (3,333 images).

Comparison

Model	Top-1	Top-5
This model (DINOv2-base)	84.5%	97.0%
CLIP zero-shot (no training)	32.8%	77.4%

Usage

from transformers import pipeline

classifier = pipeline("image-classification", model="dubattim/aviation-intelligence-vit-fgvc")
results = classifier("photo.jpg", top_k=5)
print(results)
# [{'label': 'A380', 'score': 0.78}, {'label': 'A340-600', 'score': 0.05}, ...]
