Weather-Image-Classification

Weather-Image-Classification is a vision-language model fine-tuned from google/siglip2-base-patch16-224 for multi-class image classification. It is trained to recognize weather conditions from images using the SiglipForImageClassification architecture.

Label Space: 5 Classes

The model classifies an image into one of the following weather categories:

"id2label": {
  "0": "cloudy/overcast",
  "1": "foggy/hazy",
  "2": "rain/storm",
  "3": "snow/frosty",
  "4": "sun/clear"
}
