Model Card for MITLL/LADI-v2-classifier-large
LADI-v2-classifier-large is based on microsoft/swinv2-large-patch4-window12to16-192to256-22kto1k-ft and fine-tuned on the MITLL/LADI-v2-dataset. LADI-v2-classifier is trained to identify labels of interest to disaster response managers from aerial images.
📘 NOTE 📘 This model is the main version of the large model which is trained on all splits of the LADI v2 dataset. It is intended for deployment and fine-tuning purposes. If you are interested in reproducing the results of our paper, see the 'reference' versions of the classifiers MITLL/LADI-v2-classifier-small-reference and MITLL/LADI-v2-classifier-large-reference models, which are trained only on the training split of the dataset.
Model Details
Model Description
The model architecture is based on swinv2 and fine-tuned on the LADI v2 dataset, which contains 10,000 post-disaster aerial images from 2015-2023 labeled by volunteers from the Civil Air Patrol. The images are labeled using multi-label classification for the following classes:
- bridges_any
- buildings_any
- buildings_affected_or_greater
- buildings_minor_or_greater
- debris_any
- flooding_any
- flooding_structures
- roads_any
- roads_damage
- trees_any
- trees_damage
- water_any
How to Get Started with the Model
LADI-v2-classifier-large is trained to identify features of interest to disaster response managers from aerial images. Use the code below to get started with the model.
The simplest way to perform inference is using the pipeline interface
from transformers import pipeline
image_url = "https://fema-cap-imagery.s3.amazonaws.com/Images/CAP_-_Flooding_Spring_2023/Source/IAWG_23-B-5061/A0005/D75_0793_DxO_PL6_P.jpg"
pipe = pipeline(model="MITLL/LADI-v2-classifier-large")
print(pipe(image_url))
[{'label': 'buildings_any', 'score': 0.9994631409645081},
{'label': 'bridges_any', 'score': 0.9981274008750916},
{'label': 'flooding_structures', 'score': 0.9974740147590637},
{'label': 'roads_any', 'score': 0.9966784715652466},
{'label': 'water_any', 'score': 0.9921613335609436},]

img_data = requests.get(image_url).content
img = Image.open(BytesIO(img_data))
processor = AutoImageProcessor.from_pretrained("MITLL/LADI-v2-classifier-large")
model = AutoModelForImageClassification.from_pretrained("MITLL/LADI-v2-classifier-large")
inputs = processor(img, return_tensors="pt")
with torch.no_grad():
logits = model(**inputs).logits
predictions = torch.sigmoid(logits).detach().numpy()[0]
labels = [(model.config.id2label[idx], predictions[idx]) for idx in range(len(predictions))]
print(labels)
