Model Card for MITLL/LADI-v2-classifier-large-reference

LADI-v2-classifier-large-reference 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.

🔴 IMPORTANT ❗🔴 This model is the 'reference' version of the model, which is trained on 80% of the 10,000 available images. It is provided to facilitate reproduction of our paper and is not intended to be used in deployment. For deployment, see the MITLL/LADI-v2-classifier-small and MITLL/LADI-v2-classifier-large models, which are trained on the full LADI v2 dataset (all splits).

Model Details

Model Description

The model architecture is based on swinv2 and fine-tuned on the LADI v2 dataset, which contains 10,000 aerial images 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

This 'reference' model is trained only on the training split, which contains 8,000 images from 2015-2022. It is provided for the purpose of reproducing the results from the paper. The 'deploy' model is trained on the training, validation, and test sets, and contains 10,000 images from 2015-2023. We recommend that anyone who wishes to use this model in production use the main versions of the models MITLL/LADI-v2-classifier-small and MITLL/LADI-v2-classifier-large.

How to Get Started with the Model

LADI-v2-classifier-large-reference 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-reference")
print(pipe(image_url))

[{'label': 'buildings_any', 'score': 0.9995228052139282},
 {'label': 'water_any', 'score': 0.9990286827087402},
 {'label': 'flooding_structures', 'score': 0.9974568486213684},
 {'label': 'roads_any', 'score': 0.9963797926902771},
 {'label': 'flooding_any', 'score': 0.9872690439224243}]

For finer-grained control, see below:

from transformers import AutoImageProcessor, AutoModelForImageClassification
import torch
import requests
from PIL import Image
from io import BytesIO

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"

img_data = requests.get(image_url).content
img = Image.open(BytesIO(img_data))

processor = AutoImageProcessor.from_pretrained("MITLL/LADI-v2-classifier-large-reference")
model = AutoModelForImageClassification.from_pretrained("MITLL/LADI-v2-classifier-large-reference")

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)
